How many electrons in an atom may have the folling quantum numbers?(a)

1.	How many electrons in an atom may have the folling quantum numbers?(a)n=4,m_s=-(1)/(2)(b)n=3,l=0
Answer» Solution :(a) For n=4 Total NUMBER of elctorns =`2n^(2)2xx16=32` Half out these will have`m_s=-(1)/(2)` `therefore`Total electrons with `m_s(-(1)/(2))=16` (b) For n=3 `l=0,m_l=0,m_s=+(1)/(2),-(1)/(2)("TWO "e^(-))`
