Asked by admin @ 17/08/2021 in Chemistry viewed by 329 People

In hydrogen atom, energy of first excited state is -3.4eV. Then find out KE of same orbit of hydrogen atom

Answered by admin @ 17/08/2021

KE is the energy with which the electron moves in the orbit hence The energy is same but positive so answer is 3.4eV
