How to Write Electron Configuration for Hydrogen (H)
Hydrogen(H) has atomic number 1 and mass number 1.008 .
Since the hydrogen has only one electron around the nucleus of an atom .Therefore, hydrogen electronic configuration is very simple and easy to write.
Electronic configuration of H= 1s1
As we know that the K-shell has only one s-subshell .
s-subshell can accommodate a maximum of 2 electrons so the one electron in hydrogen atom fill in 1s subshell.
