Write the electron configuration for an element that has 2 electron, both in the first principal energy level

Explanation:

The s subshell has 1 orbital that can hold up to 2 electrons, the p subshell has 3 orbitals that can hold up to 6 electrons, the d subshell has 5 orbitals that hold up to 10 electrons, and the f subshell has 7 orbitals with 14 electrons. The first three quantum numbers of an electron are n=1, l=0, ml=0.
