When
alpha particle is accelerated at the potential V;
K.E
= 2eV
Angular
momentum L = n h
For
n = 4, L = 4h = 4h /2 π
=2h/ π
The
ionization potential is
The
radius of the nth orbit is rn
= n2r0
rn ∝ n2
r1:r2:r3 = 1:4:9
It
provide the centripetal force.
Surface
area = 4πR2
R=R0A1/3
Surface
area = 4π(R0A1/3)2
area
∝ A2/3
