Question

An orbit electron in the ground state of hydrogen has an angular momentum `L_(1)`, and an orbital electron in the first orbit in the ground state of lithium (dounle ionised positively) has an angular momentum `L_(2)`. Then :
A. `L_(1)=L_(2)`
B. `L_(1)=3L_(2)`
C. `L_(2)=3L_(1)`
D. `L_(2)=9L_(1)`

Answer 1

Correct Answer - A
Orbital angular momentum `L=(nh)/(2 pi)` is independent of Z.
