Question

The orbital frequency of an electron in the hydrogen atom ______.

Options

• increases as n increases

• decreases as n increases

• remains same throughout

• first increases then decreases with an increase in n.

Answer 1

The orbital frequency of an electron in the hydrogen atom decreases as n increases.

Explanation:

As, time period, T ∝ n³

⇒ `1/"Frequency (f)" ∝ n^3`

⇒ f ∝ n^-3

Thus, f decreases with the increase in n or vice-versa.
