The energy of an electron in the 2s orbital of a hydrogen atom is calculated using the formula En = -RZ²/n², where R is the Rydberg constant, Z is the atomic number, and n is the principal quantum number. For hydrogen, Z equals 1 and n equals 2, leading to an energy value of En = -13.6 eV. If the calculated energy does not match expectations, the issue may lie in the application of the formula or the values used in the calculation.

If you don't tell us what answer you got, it is difficult to say why it is wrong.mahrap said:What is the energy of an electron in the 2s orbital of a hydrogen atom?
I thought En = -RZ^2 / n^2
Why am i not getting the right answer with
Z = 1
n = 2
and R just the value of the constant
