The model below shows a calcium atom. an image has a mix of red and blue balls in its center and 4 concentric black rings around the center. the first ring from the center has 2 small green balls on it. the second ring has 8 small green balls on it. the third ring has 8 small green balls on it. the outermost ring has 2 small green balls on it. how many electrons are in the third energy level? 2 8 18 20

8

Explanation:

The neutral calcium atom has 20 protons and 20 electrons. The first energy level holds a  maximum 8 electrons. The second energy level can only hold a maximum of The third energy level, in small atoms like the calcium atom, can only hold a maximum of 8 electrons.

Note: In bigger atoms, the third energy level can hold a maximum of 18 electrons.
