Question

The energy of electron in first bohr's orbit of hydrogen atom is -13.6 ev what will be its potential energy in n is equal to fourth orbit

Answer 1

Answer:

-3.4 eV

Explanation:

The energy of electron in nth orbit is calculated by the formula

E = -13.6 Z²/n² eV, where Z is the atomic mass and n is the no. of the orbit.

So in the 4th orbit of hydrogen atom,

⇒ E = -13.6* 1²/2² eV

⇒ E = -13.6 /4 eV

⇒ E = -3.4 eV

Answer 2

Answer:

answer is as -1.70 ev
