Which of the following (n, l, ml, ms) combinations is impossible for an electron in an atom? a.
6, 2, 0, 1/2

b.
3, 1, 1, −1/2

c.
3, 2, −2, −1/2

d.
3, 1, −2, 1/2

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
