Question

Find out the maximum number of electrons that can involve in the shielding of an electron,having quantum numbers :n=2,l=1,m=0,m(s)=+(1)/(2), in an atom​

Answer 1

Answer:

If n=4, azimutal quantum no. l can have the valves l=3(f),2(d),1(p),0(s) orbitals,

For a given l,m=+l to −l

∴ When lm=+1, l(f),2(d),(1(p).

∴3 of them have same m=+1 . A given no. of m represents an orbital & an orbital contains 2e

−

s.

∴ Total number of electrons in atom that can have n=4 m=+1 are 3×2=6.
