Question

the number of electrons in Na,having n+1=3 will be​

Answer 1

Explanation:

As we know,

principal quantum number ⇒ denoted by (n)→wheren=1,2,3

azimuthal quantum number ⇒ denoted by (ℓ)→whereℓ=0ton+1

magnetic quantum number ⇒ denoted by (m)→wherem⇒−ℓtoℓ

spin quantum number ⇒ denoted by (s)→wheres⇒±1/2

Na

+

=1s

2

2s

2

p

6

As we know,

s have l = 0 and p

z

have m=0

So, it have six electron with (n×l×m)=0.
