Identify the atom whose electron configuration is [Ar] 3d^5 4s^1.

A) Write the one or two-letter symbol for the element.

B) how many unpaired electrons are there in the ground state of this atom?

Expert Solution

Count electrons

Z = Ar + 5+1 = Ar + 6 = 18+6 = 23

this must be Vanadium

a)

V

b)

unpaired electrons --> from d

5 are unpaired

from s

1 is unpaired

total = 5+1 = 6
