We are being asked how many electrons are unpaired in the ground-state electron configuration of Arsenic (As). To figure that out, let’s first write the electron configuration of a neutral (uncharged) As atom.
Ground-state means that Iron is in its lowest energy form (not in an excited state).
Neutral element: Atomic number = # protons = # of electrons
Neutral Arsenic (As):
• Atomic number = 33
• # of electrons = 33 e-
There are _____ unpaired electrons in ground state arsenic (As).
e. none of the above
