(The 2 p subshell holds six electrons.) The number of electrons (13) is correct. The electron configuration should be 1 s 2 2 s 2 2 p 6 3 s 2 3 p 1 . The configuration shown might be an excited state of an aluminum atom. For boron, there are too many electrons. (Boron only has five electrons.) The electron configuration should be 1 s 2 2 s 2 2 p 1 . What would be the electric charge of a boron ion with the electron arrangement given in the problem?
