Question

The amount of energy required to promote electron from first energy level to third energy level (in terms of joule/mol) for Hydrogen atom is (here * represents power) ?


11.66 × 10*5 J/mol

-11. 66× 10*5

14.68×10*5

-14. 68× 10*5

​

Answer 1

Answer:

Correct option is C)

Energy of e− in nth shell =−13.6n2τ2

For H−atom with n=3→E=−13.6×91

⇒E=91 (Energy of e− in first shell)

⇒E=91×2.18×10−18

⇒E=2.42×10−19J(Ionisation Energy= Energy of e− in first shell)
