Problem: What element has the electron configuration 1s2 2s2 2p6 3s2 3p2?

FREE Expert Solution

When finding the identity of the element, you’ll have to identify the atomic numberof that element. Recall that every single element in the periodic table has a corresponding atomic number.

The atomic number of an element is always equal to the number of protons of that element. And when the element is neutral (charge = 0), the number of protons is equal to the number of electrons.

Neutral element:          Atomic number = # protons = # of electrons
