Answer 1

Aufbau principle states that : In the ground state of the atoms, the orbital are filled in increasing order of their energies.

i.e electrons first occupy the lowest energy orbital available to them and enter in the higher energy orbital only after the lower energy orbitals are filled.

The order in which the electrons are filled is :

1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p.. and so on
