How many electrons occupy p orbitals in a(n) bismuth atom?
? =electrons

33 p eletrons would be the total. 
If you look at the electron configuration for Bi, it is [Xe] 6s2 4f14 5d10 6p3. Note that the 1p, 2p, 3p, 4p, and 5p orbitals (3 of each type) are all full. That's 15 p orbitals x 2 electrons per orbital = 30 electrons. Add to that the three 6p electrons for a total of 33 p electrons.
