Solution: Which element has the most unpaired electrons in the orbital set indicated by parentheses?a. carbon (p)b. barium (s)c. oxygen (p)d. vanadium (d)e. chlorine (p)

Problem

Which element has the most unpaired electrons in the orbital set indicated by parentheses?

a. carbon (p)

b. barium (s)

c. oxygen (p)

d. vanadium (d)

e. chlorine (p)

Solution

Construct the electron configuration of the valence electrons of each atom given and determine which has the most # of unpaired electrons 

To find the number of unpaired electrons, fill up the electrons before the valence electrons. All of the electrons in lower energy orbitals are paired.
