Question

Calculate the excitation energy required for the promotion of electron from the ground state of Hydrogen atom to the fourth energy level?​

Answer 1

Explanation:

Energy required for the promotion of electron from the ground state to fourth energy level is given as,

ΔE = 2.18×10−18(1n12−1n22)ΔE = 2.18×10−18(112−142)ΔE = 2.18×10−18×0.9375ΔE = 2.04×10−18 J
