Q. Define: 1 amu
One atomic mass unit is thinks as one twelfth of the mass of carbon atom 6 C 12.
1 amu = 1.66 X 10 -27 kg.
Q. Define: mass defect.
The dissimilarity in the total mass of the nucleons and the actual mass of the nucleus is known as the mass defect.
Pauli exclusion principle (W. Pauli; 1925) No two similar fermions in a system, like electrons in an atom, can have an equal set of quantum numbers.
