Classification of Atoms and Ions

This video tutorial by Earth Pen discusses the classification of atoms based on electrical charges, focusing on ions and isotopes. It explains the structure of atoms, including subatomic particles like electrons, protons, and neutrons. The video details how atoms can become ions by gaining or losing electrons, forming cations and anions. It also covers isotopes, which are variations of atoms with the same atomic number but different atomic masses due to varying neutron numbers. The tutorial uses hydrogen as an example to illustrate these concepts.

What is the main topic of the video series introduced in the beginning?

• The classification of atoms into ions and isotopes

• The classification of planets

• The study of molecules

• The history of chemistry

Which subatomic particle is positively charged?

• Proton

• Neutron

• Photon

What happens to an atom when it loses an electron?

• It becomes an anion

• It becomes a cation

• It becomes an isotope

• It becomes a neutral atom

Which of the following is a negatively charged ion?

• Cation

• Anion

• Proton

• Neutron

What is a monatomic ion?

• An ion with a variable charge

• An ion made up of a single atom

• An ion with no charge

• An ion made up of multiple atoms

How do polyatomic ions differ from monatomic ions?

• They are always positively charged

• They are always negatively charged

• They are made up of multiple atoms

• They have no charge

What remains unchanged in isotopes of the same element?

• Number of electrons

• Number of neutrons

• Atomic mass

• Number of protons

Which isotope of hydrogen has one neutron?

• Protium

• Deuterium

• Tritium

• Hydronium

What is the atomic mass of tritium?

• 2

• 1

• 4

• 3

Which of the following is NOT a characteristic of isotopes?

• Different atomic masses

• Same atomic number

• Same element

• Different number of protons
