What is formed after an atom gains electron/s?​

Sagot :

Answer:

ion

Explanation:

When an atom gains/loses an electron, the atom becomes charged, and is called an ion

Explanation:

Adding electrons creates an ion that is larger then the neutral atom; removing electrons produces an ion that is smaller then the neutral atom. When electrons are added, mutual repulsions push them apart and they occupy a larger volume so the ion increases in size.
