El final de la tabla periódica es TERRORÍFICO
TLDRThis script delves into the fascinating world of the periodic table, highlighting the 118 chemical elements that constitute all matter, including our bodies. It explains the atomic structure, emphasizing the role of protons and neutrons in forming stable atoms. The video clarifies that only the first 90 elements are naturally found, while the heavier, radioactive ones at the table's end are unstable and transform into lighter elements over time. It humorously illustrates the impossibility of a universe with only hydrogen atoms and touches on the creation of super-heavy elements in particle accelerators, emphasizing their fleeting existence and the energy released during their decay.
Takeaways
- 📚 The periodic table is a grid that organizes the 118 chemical elements that make up everything around us, including our bodies and the air we breathe.
- 🧲 Elements at the beginning of the periodic table, such as aluminum, iron, and sulfur, are more commonly found in nature compared to those at the end, like livermorium, moscovium, and oganesson.
- 🚫 Only the first 90 elements of the periodic table are naturally found, with the rest being artificially created and often highly radioactive.
- ⚛️ Atoms consist of a nucleus with protons and neutrons, with the number of protons defining the element's identity.
- ♿ Hydrogen is the simplest element with a single proton, occupying the first place in the periodic table.
- 🔝 As we move across the periodic table, the increase in the number of protons results in different elements with varying properties and appearances.
- 💥 Protons repel each other due to their positive charge, and without neutrons, they would not be able to form stable atomic nuclei.
- 🥊 Neutrons provide the necessary force to keep protons together in the atomic nucleus through the strong nuclear force.
- 🚫 The power of neutrons is limited; beyond 84 protons, no amount of neutrons can stabilize the nucleus, leading to the formation of radioactive elements.
- ⏳ Radioactive elements, especially those at the end of the periodic table, are unstable and continuously lose protons, transforming into lighter elements over time.
- 🔬 The rate of radioactive decay varies among elements, with some taking millions of years while others transform in milliseconds.
- 🧪 The most unstable elements at the end of the periodic table are so fleeting that they are only observed artificially in particle accelerators.
- 💥 If a gram of oganesson, the heaviest known element, were created, it would release an enormous amount of energy and radioactive particles within seconds, illustrating the danger of these elements.
Q & A
What is the periodic table and what does it represent?
-The periodic table is a grid that organizes the 118 known chemical elements, representing all the matter that makes up our bodies and everything around us, including water, air, and rocks.
Why are some elements at the end of the periodic table not found in nature?
-Elements at the end of the periodic table, such as Livermorium, Mendelevium, or Oganesson, are not found in nature because they are radioactive and have extremely short half-lives, making them too unstable to exist naturally.
What distinguishes one element from another in terms of atomic structure?
-The number of protons in the atomic nucleus distinguishes one element from another. For example, hydrogen has one proton, helium has two, and so on.
Why can't atoms with more than 84 protons be stable?
-Atoms with more than 84 protons are unstable because the repulsive force between protons, which all have a positive charge, cannot be overcome by the strong nuclear force that also acts within the nucleus, leading to radioactive decay.
What role do neutrons play in an atom's nucleus?
-Neutrons, which have no electric charge, help to maintain the stability of an atom's nucleus by attracting protons through the strong nuclear force, overcoming the repulsion between protons.
How do radioactive elements transform over time?
-Radioactive elements transform over time by losing particles, such as groups of two protons and two neutrons or individual electrons, which results in a change in the number of protons and thus the element's identity.
What is the significance of the number of protons in determining an element's identity?
-The number of protons is the key factor in determining an element's identity. When an element loses or gains protons through radioactive decay, it transforms into a different element.
How can we observe elements with very short half-lives that do not occur naturally?
-We can observe elements with very short half-lives by producing their atoms artificially in particle accelerators, where lighter atoms are bombarded into heavier ones, potentially creating new elements.
What would happen if we were to create a gram of Oganesson, the element with the most protons?
-If we created a gram of Oganesson, it would be so unstable that all of its atoms would decay into Livermorium within the first second, releasing a massive amount of energy and alpha particles.
Why is it beneficial that we cannot find the heaviest elements of the periodic table in our environment?
-It is beneficial because these elements are highly radioactive and unstable, releasing large amounts of energy and radiation upon decay, which would be extremely hazardous to life if present in our environment.
How does the script relate to the promotion of a VPN service at the end?
-The script uses an analogy of navigating the internet safely with a VPN service, similar to how we benefit from not being exposed to the most radioactive elements in our environment, by providing security and access to restricted content.

🌌 La Tabla Periódica y los Elementos Químicos
El primer párrafo introduce la tabla periódica como una cuadrícula que agrupa a los 118 elementos químicos que constituyen la materia, incluyendo nuestro cuerpo y el entorno. Se menciona que solo los primeros 90 elementos son comunes en la naturaleza, mientras que los que quedan, como el libermorio, el mendelevio o el loganesón, son raros y peligrosos debido a su radiactividad. El núcleo atómico está compuesto por protones y neutrones, y la diferencia entre los elementos radica en el número de protones. El hidrógeno, con un solo protón, ocupa la primera posición, y a medida que avanzamos, el número de protones aumenta, dando lugar a elementos con propiedades y apariencias distintas. Se destaca la repulsión entre protones y cómo la fuerza nuclear fuerte, mediada por los neutrones, mantiene a los protones en el núcleo atómico, permitiendo la existencia de los 118 elementos.
⚠️ Los Elementos Radiactivos y su Inestabilidad
El segundo párrafo se enfoca en la inestabilidad de los elementos con más de 84 protones, que son radiactivos y se desintegran continuamente. Se explica que los elementos del final de la tabla periódica, como el uranio y el plutonio, tienen tiempos de desintegración muy largos, pero hay otros con protones en cantidad suficiente para ser extremadamente inestables, transformándose en otros elementos en cuestión de milisegundos. Estos elementos efímeros no se encuentran en la naturaleza y solo pueden ser observados a través de la creación artificial en aceleradores de partículas. Se ilustra cómo la probabilidad de fusionar átomos pesados es muy baja, y cómo los elementos con muchos protones se desintegran rápidamente, lo que impide la creación de cantidades observables de ellos. El párrafo también imagina el efecto catastrófico de crear un gramo de oganesón, el elemento con más protones, y cómo su desintegración inmediata liberaría una gran cantidad de energía y radiación.
🛡️ Seguridad en Internet con North VPN
El tercer párrafo cambia de tema y presenta North VPN como un servicio que ofrece navegación anónima y segura en internet, con la capacidad de acceder a contenido restringido y bloquear sitios web y archivos maliciosos. Se menciona que el servicio también proporciona una barrera adicional contra la publicidad invasiva.

Highlights
The periodic table contains 118 chemical elements that make up all matter, including our bodies, water, air, and rocks.
Only the first 90 elements in the periodic table are naturally found, while the rest are synthetic and highly radioactive.
The number of protons in an atom's nucleus is what distinguishes one element from another.
Hydrogen is the simplest element with a single proton, occupying the first position in the periodic table.
As the number of protons increases, so do the properties and appearance of the elements.
Protons repel each other due to their positive charge, preventing the formation of atoms with more than one proton without a binding force.
Neutrons provide the binding force that holds protons together in an atom's nucleus through the strong nuclear force.
The power of neutrons is limited, and when an atom has more than 84 protons, it becomes unstable and radioactive.
Radioactive elements continuously emit particles, which can be alpha particles or electrons, transforming into lighter elements.
The rate of radioactive decay depends on the instability of the element, with some taking millions of years and others mere milliseconds.
Elements with more protons are so unstable that they transform into other elements almost instantly.
The heaviest elements can only be produced artificially in particle accelerators by bombarding heavy elements with lighter atoms.
The production of the heaviest elements is extremely rare, with only one atom created per week on average.
If a gram of oganesson, the element with the most protons, could be created, it would instantly decay into other elements, releasing massive energy.
The decay of such heavy elements would result in an explosion and a cloud of hot, radioactive dust.
Most radioactive elements are not as unstable or emit as much energy as oganesson, but they can still be deadly if encountered.
The absence of heavy elements in our environment is beneficial for our safety and health.
NordVPN is mentioned as a service that provides internet security, anonymity, and access to restricted content, with additional features like blocking malicious files and intrusive ads.
