There are 2 unpaired electrons in the 2p sublevel of the atom shown. c. 1s 2 2s 2 2p ANS: The 3 in 2p 3 indicates that three electrons are in the p orbitals of the second energy level. 38. ANS: Their locations in the periodic table indicate that phosphorus and sulfur are nonmetals and sodium is a metal. Nonmetals are a group with characteristic properties, so phosphorus and sulfur are the most similar elements of the three. 39.
