Ions and Isotopes | Chemistry Animation
TLDRThe video script from Earth Pen delves into the classification of atoms, focusing on ions and isotopes. It explains that atoms, the building blocks of matter, are composed of electrons, protons, and neutrons. An element is a collection of atoms with the same number of protons, leading to the creation of the periodic table. Atoms become ions when they gain or lose electrons, resulting in cations (positively charged) or anions (negatively charged). The script uses hydrogen as an example to illustrate these concepts, showing how it can become an ion by adding or removing electrons. It also introduces monatomic and polyatomic ions, which are single-atom or multi-atom entities with a net charge. The concept of isotopes is then explored, where atoms of the same element have different numbers of neutrons, leading to variations in atomic mass without changing the element's identity. The isotopes of hydrogen—deuterium, protium, and tritium—are used to clarify this point. The video concludes by encouraging viewers to support the channel for more educational content.
Takeaways
- 🌐 Atoms are the fundamental building blocks of matter, consisting of subatomic particles including electrons, protons, and neutrons.
- 🔬 An element is a collection of atoms with the same number of protons, which is unique and constant for each element.
- ⚖️ Atoms with the same number of electrons and protons are neutral, as the charges balance each other out.
- ⚡ When an atom gains or loses electrons, it becomes an ion with a net electrical charge, either positive (cation) or negative (anion).
- 💧 Adding an electron to a neutral atom results in an anion, while removing an electron results in a cation.
- 📊 There are two types of ions: monatomic ions, which consist of a single atom, and polyatomic ions, which consist of two or more atoms.
- 🏷 Common monatomic and polyatomic ions are listed in tables, which can be encountered in everyday life.
- 🧬 Isotopes are variations of an atom with the same atomic number but different atomic masses due to varying numbers of neutrons.
- 🎚 Isotopes do not change the element itself, only the number of neutrons, which affects the atomic mass but not the number of protons or electrons.
- 💦 Hydrogen serves as an example for isotopes, with deuterium, protium, and tritium being specific types of hydrogen isotopes.
- 📝 Deuterium, protium, and tritium differ in their neutron count, with deuterium having one neutron, protium having none, and tritium having two.
Q & A
What are the three subatomic particles that make up an atom?
-The three subatomic particles that make up an atom are electrons (negatively charged particles), protons (positively charged particles), and neutrons (neutrally charged particles).
What is the difference between an atom and an element?
-An element is composed of a distinct type of atom, which is made up of a specific number of protons. An atom is the basic unit of an element, and the number of protons in an atom defines the element.
What is a neutral atom and why is it called neutral?
-A neutral atom is an atom with the same number of electrons and protons. It is called neutral because the opposite electrical charges cancel each other out, resulting in no net electrical charge.
What is the term for an atom that has gained or lost electrons and carries a certain electrical charge?
-An atom that has gained or lost electrons and carries a certain electrical charge is called an ion.
How does the removal or addition of electrons affect the charge of a hydrogen atom?
-If a neutral hydrogen atom loses an electron, it becomes a positively charged ion known as a cation. Conversely, if a neutral hydrogen atom gains an electron, it becomes a negatively charged ion known as an anion.
What are the two types of ions that can be encountered in real life?
-The two types of ions encountered in real life are monatomic ions, which are made up of only one atom, and polyatomic ions, which are made up of two or more atoms and carry an electrical charge.
What is the difference between isotopes and how does it affect the element?
-Isotopes are variations of an atom with the same atomic number but different atomic masses due to varying numbers of neutrons. This difference does not change the element itself, as the number of protons and electrons remains the same.
What are the names and properties of the three isotopes of hydrogen?
-The three isotopes of hydrogen are protium (1 proton and 0 neutrons, atomic mass of 1), deuterium (1 proton, 1 neutron, atomic mass of 2), and tritium (1 proton, 2 neutrons, atomic mass of 3).
How does the variation in the number of neutrons affect an atom's properties?
-The variation in the number of neutrons affects an atom's atomic mass but does not change the element's identity or its chemical properties, as the number of protons, which defines the element, remains constant.
Why is the number of protons in an atom considered fixed or unchanging?
-The number of protons in an atom is fixed because it defines the element. A change in the number of protons would result in a different element with distinct chemical properties.
What is the role of the electron in determining the electrical charge of an atom?
-The electron plays a crucial role in determining the electrical charge of an atom. If the number of electrons equals the number of protons, the atom is neutral. If there are more electrons than protons, the atom becomes an anion (negatively charged), and if there are fewer electrons than protons, the atom becomes a cation (positively charged).
How does the concept of isotopes relate to the stability of an atom?
-Isotopes can vary in stability due to the differences in the number of neutrons. Some isotopes are stable, while others are unstable and can undergo radioactive decay to reach a more stable state with a different number of neutrons.

🔬 Understanding Atoms: Ions and Isotopes
This paragraph introduces the topic of atoms, specifically focusing on their classification based on electrical charges, resulting in ions and isotopes. It explains that atoms, as the building blocks of matter, are composed of subatomic particles: electrons (negatively charged), protons (positively charged), and neutrons (neutral). The distinction between atoms and elements is clarified, with elements being unique types of atoms defined by a specific number of protons. The concept of neutral atoms, cations, and anions is introduced, along with examples using hydrogen. Additionally, the paragraph distinguishes between monatomic and polyatomic ions and introduces the concept of isotopes, which are variations of an atom with the same atomic number but different atomic masses due to varying neutron counts. Hydrogen is used as an example to illustrate different isotopes such as protium, deuterium, and tritium.
