|
Answer» Solution :State and explain Pauli.s EXCLUSION principle states that "No two electrons in an atom can have the same SET of values of all four QUANTUM numbers" lllustration:H(Z=1)`1s^1` One electron is present in hydrogen Z=2.He: `1s^2`.In this one electron has the quantum NUMBER same as is different .i.e. n=1,l=o,m=o and s =+1/2.For other electron,fourht q uantum number is different i.e.n=1l=0,m=o and s=-1/2. |
