There is no element with one valence electron and six energy levels. Only two valence electrons and six energy levels.

Answer:

Calcium

Explanation:

A: Calcium is a group 2 element with two valence electrons. Therefore, it is very reactive and gives up electrons in chemical reactions. It is likely to react with an element with six valence electrons that “wants” to gain two electrons. This would be an element in group 6, such as oxygen.
