Answer:

1.anion

2.Valency

Explanation:

When an atom gains/loses an electron, the atom becomes charged, and is called an ion. Gaining an electron results in a negative charge, so the atom is an anion. Losing an electron results in a positive charge, so atom ion is a cation.

Valence is the number of electrons the atom loses or gains to have a complete outer shell (it is always the. lowest number). If an atom donates (gives), or accepts (takes) , or shares electrons, the atom is active.
