Each orbit is assigned a quantum number, n, starting with n or the orbit closest to the nucleus. The energy of an electron is inversely proportional to n squared Calculate the energy of an electron in the n-8 orbit. Number Calculate the energy of an electron in the n orbit.

Explanation / Answer

a)

En= -13.6/n2   eV

for n=8

E = -13.6 /82 = -13.6/64 = 0.2125 eV

since 1eV =1.6*10-19J

E=0.2125 * 1.6*10-19= 3.4*10-20 J

b)

En= -13.6/n2   eV

for n=infinirt

E = -13.6 /infinity2 = -13.6/infinity= 0

E= 0 J
