Question

The total energy of electron in the ground state
of hydrogen atom is – 13.6 eV. The kinetic energy
of an electron in the first excited state is
(a) 6.8 eV (b) 13.6 eV
(c) 1.7 eV (d) 3.4 eV

Answer 1

Answer:

option b 13.6

Explanation:

energy infinity- energy of grnd state

Which is 0-(-13.6) = 13.6 ( option b)
