How many electron in an atom may have the following quantum number ?
a. `n = 4, m_(s) = -(1)/(2)`
b. `n = 3,l = 0`

Text Solution

Verified by Experts

a. `2n^(2)=2xx4^(2)=32`
But only one spin`=32/2=16e^(-)`
b. `3s, s` can have only `2e^(-)`

An electron in an atom can be completely designated with the help of four quantum numbers. Out of these, the first three i.e., principal (n), azimuthal (l) and magnetic (m) quantum number are obtained from the solution of Shrodinger wave equation while the spin(s) quantum number arises from the spin of the electron around its axis clockwise or antiaclockwise. Ot of these principal quantum number tells about the size, azimuthal quantum number about the shape and magnetic quantum signifies the orientation of the electron orbital.
