Number of energy levels in Hydrogen
How many energy levels are there in Hydrogen?
E = -E0n2
It is important to know that the electron in a Hydrogen atom can only have certain energies. These energies are called the Hydrogen’s â€œenergy levelsâ€. Not too many people know that the different energy levels of a Hydrogen atom are given by the equation:
|E = –||E0|
where E0 = 13.6 eV (1 eV = 1.602Ã—10-19 Joules) and n = 1,2,3â€¦ and so on so that the ground state has energy E1= -13.6 eV and the second energy level (the first excited state) has energy E2 = -13.6/4 eV = -3.4 eV.
