electrons are filled from the lowest energy level to the highest energy level
electrons are assumed to occupy spaces called orbitals.
electrons are filled into energy shells starting from the 1st energy shell
s orbital can occupy maximum of 2 electrons
p orbital can occupy maximum of 6 electrons
d orbital can occupy maximum of 10 electrons
1st energy shell has the s orbital
2nd energy shell has s and p orbitals
3rd energy shell has s,p and d orbitals
4th energy shell has s,p, d and f orbitals
the atomic number of given element is 32 and the 32 electrons are filled in to orbitals as follows
1s : 2
2s : 2
2p : 6
3s : 2
3p : 6
4s : 2
3d : 10
4p : 2
5s : 0
