Question

If the potential energy in ground state of a hydrogen atom is considered to be zero, then find the total energy is first excited state

Answer 1

atom has very important for the mulequels

Answer 2

Answer:

-6.8eV

Explanation:

Total energy in first excited state, n=2

= -13.6÷4

= -3.4 eV

This is the sum of 3.4eV(Kinetic energy) and -6.8eV(Potential energy)

Since potential energy in the first excited state is to be zero, a +6.8eV is added to the total energy ie all enrgy levels must be added with +6.8eV

Thus total energy in ground state becomes -13.6 + 6.8 = -6.8eV
