Question

In hydrogen atom, the product of the angular momentum and the linear momentum of the electron is proportional to (n = principal quantum number) ____________.

Options

• n²

• n⁰

• n¹

• n³

Answer 1

In hydrogen atom, the product of the angular momentum and the linear momentum of the electron is proportional to n⁰.

Explanation:

In hydrogen atom `"v" prop 1/"n"`

`"P" = "mv" prop 1/"n"`

According to Bohr's postulate

`"Angular momentum L" = "n" "h"/(2pi)`

`therefore "P" xx "L" = "n"^0`
