Question

What is the energy (EV) of a first excited state of hydrogen? ​

Answer 1

Answer:

For the first excited state, n = 2. Hence the value of energy for the first excited energy of hydrogen atom is −3.40eV.

Explanation:

hope it is

Answer 2

Answer:

Excited state is defined as the energy state which is higher than the ground state. For the first excited state, n = 2. Hence the value of energy for the first excited energy of hydrogen atom is −3.40eV.
