a) Aufbau principle states that atoms are filled into orbitals according to increasing energy of the orbitals.

b) pauli exclusion principle states that no more than two atoms are filled in an orbital and the atoms must have opposite spin.

Answer 2

Answer:

A. The Pauli exclusion principle is the quantum mechanical principle which states that two or more identical fermions (particles with half-integer spin) cannot occupy the same quantum state within a quantum system simultaneously.

B. This principle was formulated by Austrian physicist Wolfgang Pauli in 1925 for electrons, and later extended to all fermions with his spin–statistics theorem of 1940.
