Question

If n is the orbit number of the electron in a hydrogen atom, the correct statement among the following is

• A. Electron energy increases as n increases.
• B. Hydrogen emits infrared rays for the electron transition from $n = \infty$ to n = 1.
• C. Electron energy is zero for n = 1.
• D. Electron energy vaires as $n^{2}$

Answer 1

Answer: (A)

Electron energy increases as n increases.

Answer 2

In a hydrogen atom the energy of electron in nth orbit is

$E_{n} = - \frac{13.6}{n^{2}}eV$
