Q

Why are noble gases unreactive in terms of electronic configuration?

A

The atoms of noble gases (group VIII) already have a complete outer shell, so they have no tendency to lose, gain or share electrons.

21
Q

Precipitation?

A

2 solutions of soluble salts mix to produce an insoluble salt precipitate. Occurs when ions in solution combine to form a new compound of low solubility in water.
