Question

Give the sets of quantum number that describe an electron in a 3p

Answer 1

n=3
l=2
m= -1,0,+1
s=+1/2 or -1/2

Answer 2

very simple
u have principal quantum number(n)=3

it means electron is 3rd shell

azimuthal quantum number(l) tells us the shape of orbital
formulae for this is =n-1
but it is given that there is p orbital so l=1

magnetic quantum number tell us about orientation in which electron can be there are -1,0,1,

there are two possible spins are -1/2 or 1/2

Hope it helps!
