Which types of orbitals are found in the principal energy level n = 3?
o a. s, d.
ob. s, p, d
o c. s. p
od. s. p,f
o e. s. d, f

measure their densities same density, same sub

the answer is a. hope this .

i think its c if i'm wrong

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
