, Write the subshell electron configuration (i.e.1s2 2s2, etc.) for the P15 atom and
identify which are valence (outer shell) electrons and determine how many
valence electrons there are.
P15 = 15 electrons = 1s2 2s2 2p6 3s2 3p3 = 5 valence electrons

(indicated by the x icon on the toolbar and then choose arrows

from the window which opens).



Using up and down arrows, write the orbital diagram for the V23 atom and
identify which are unpaired electrons and determine how many unpaired
electrons there are.
V23 = 1s2 2s2 2p6 3s2 3p6 4s2 3d3
