Question

What is the velocity of 3rd orbital of li

Answer 1

Electronic configuration of Li is 1s2 2s1 2p0 because atomic no of Li is 3

3rd orbital of lithium is 2p0 which is vacant and the atomic no of lithium is 7

Then the fr of velocity is = 0.529×(n2 /Z)

Here, n is the no of shells and Z is atomic mass

Then the velocity of 3rd orbital of Li is

0.529×(3)^2/7=0.6801
