The number of nodal surfaces passing through the nucleus of 2s orbitals has to be identified. Concept introduction: Nodal surfaces: the surface which passing through nucleus where there is zero chance of finding electrons. The values of l (azimuthal quantum number) when the principal quantum number is n are from 0 to ( n − 1 ) . Each value of l indicates subshell and for l = 0 , 2 and 3 represents s, d and f subshells.
