Which of the following corresponds to the energy of the possible excited state of hydrogen?

Options

A. `-13.6eV`
B. `13.6eV`
C. `-3.4 eV `
D. `3.4eV`

Answer

C

Explanation

THE different energy leves of an atoms are given by the equation . `E_(n) =- 13.6 Z^2 //n^2eV `
Z is the atomic number for hydrogen =1
n = 1,2,3 and so on such that the ground state has n=1 and the secondart energy level ( first excited first excited state , n=2
`e=- 13.6 //2 ^2 =- 13.6 //4 =- 3.4 eV`
