Question

Define an ion . Name the ion formed when an atom gains electrons​

Answer 1

Answer:

hope it will help you

Explanation:

Positively charged ions are called cations (pronounced CAT-ions). The ions that are formed when an atom gains electrons are negatively charged because they have more electrons in the electron cloud than protons in the nucleus. Negatively charged ions are called anions (pronounced AN-ions).

Answer 2

Answer:

Anions. Some atoms have nearly eight electrons in their valence shell and can gain additional valence electrons until they have an octet. When these atoms gain electrons, they acquire a negative charge because they now possess more electrons than protons. Negatively charged ions are called anions.
