The electron configuration of an atom tells us how many electrons are in each orbital. a. True
b. False

a. True

Explanation:

Take for example the electron configuration of nitrogen:

N ⇒ 1s² 2s² 2p³

The numbers in superscript tell us the number of electrons in each orbital. This is true for all elements. In this case we can see that nitrogen has 2 electrons in the 1s orbital, 2 other in the 2s orbital, as well as 3 electrons in the 2p orbitals.
