How many outer electrons does an Oxygen atom have?

Back

Oxygen has six outer (valence) electrons.

Front

What is the significance of energy levels in an atom?

Back

Energy levels determine the distance of electrons from the nucleus and their energy; electrons in higher energy levels are further from the nucleus.
