Determine the values of all the four quantum numbers of the 8^(th) electron in O-atom and 15^(th) electron in CI atom .

Answer»

SOLUTION :Electronic configuration of oxygen=

`:. 8^(th)` electron PRESENT in `2p_(x)` ORBITAL and the quantum number are
`n = 2, l = 1 , m_1 = "either" + 1 "or" - 1 and s = -1//2`
Electronic configuration of chlorine =

`15^(th)` electron present in `3P_z` orbital and the quantum numbers are `n = 3, l = 1, m_1= ` either + 1or - 1 and ms = + 1//2.
