Question: which one of the following elements is paramagnetic in its ground state?
Answer: a) Give the atom symbols for those atoms from Z = 1 to Z = 20 that are paramagnetic in the ground electronic state. Paramagnetic atoms contain unpaired electrons; thus, the paramagnetic atoms from Z = 1 to Z = 20 are: H, Li, B, C, N, O, F, Na, Al, Si, P, S, Cl, K.
