Atoms and Ions: Let's Have Some Electric Fun!

What happens when an atom loses two electrons?

1. It becomes a positive ion

2. It becomes a negative ion

3. It becomes a positive isotope

4. It becomes a negative isotope

Answer: 1. It becomes a positive ion

Explanation: An ion is formed when an atom gains or loses electrons. A positively charged ion (cation) is formed when an atom loses electrons. Therefore, if an atom loses two electrons, it becomes a positively charged ion with a charge of +2.

Atoms and Ions

Atoms are the building blocks of matter, consisting of a central nucleus containing protons and neutrons, with electrons orbiting around it. When electrons are gained or lost from neutral atoms, ions are formed.

Cations are positively charged ions formed by the loss of electrons, making the atom electron-deficient. Anions, on the other hand, are negatively charged ions formed by the addition of electrons, making the atom electron-rich.

So, in the case of an atom losing two electrons, it becomes a cation or a positive ion. This process involves the removal of electrons, resulting in a positively charged species.

Understanding the behavior of atoms and ions is crucial in the study of chemistry, particularly when dealing with ionic compounds and their reactions.
