Question

write the values of all quantum no. of all the electron in 3Li atom

Answer 1

Explanation:

lithium has 3 electron in an atom , two electron in 1 st shell and one electron in 2 nd shell

value of quantum no of 1 st electron present in 1 st shell is

n=1

l=0

m=0

s=+1/2

value of quantum no. of 2nd electron present in 1st shell is

n=1

l=0

m=0

s=-1/2

value of quantum no. of 3rd electron present in 2 nd shell

n=2

l=1

m=-1,0,+1

s=+1/2 or -1/2
