What is the equation for the energy levels of the hydrogen atom

Answer: E = (13.6 eV) [1/nf² - 1/ni²]

En = (-13.6 eV) / n²

where n=1,2,3 ...

Explanation:

According to Bohr's theory each spcified energy value (E1, E2, E3 ...) is called energy level of the atom and the only allowable values are given by the equation

En = (-13.6 eV) / n²

The energy change (ΔE) that accompaies the leap of an electron from one energy level to another is given by equation

E = (13.6 eV) [1/nf² - 1/ni²]
