Question

the value of quantum numbers n,l,ml for 5 electron of boron is.​

Answer 1

Hey Here's your answer

Given , no. of electron in boron is 5

Therefore n that is Principal quantum number , which denotes number of orbitals

Hence , n = 3 as the electronic configuration is 1s² 2s² 3p¹

.°. l = 0,1,2 ( as l = n-1 )

and , ml = -2,-1,0,1,2 ( as - l ≤ ml ≤+l)

Hope it helps ,
