Question

write the four quantum numbers for the differentiating electron of sodium(Na)atom? ( with clear explanation please)​

Answer 1

Answer:write the four quantum numbers for the differentiating the electron sodium(Na)

Explanation:

The atomic number(Z) of Na is 11.

So the electronic configuration is,

1s2 , 2s2 , 2p6 , 3s1.

Here we consider 3s1.

The four quantum numbers are,

n=3,

Because in 3s1, "the principle quantum number(n)" is 3.

I=0,

Because in "angular-momentum quantum number" , s=0,p=1,d=2,f=3.

So here in 3s1, s=0.

Ml=0,

Because l=0,so Ml=0.

Ms= -1/2

Because,according to"Spin quantum number" in electronic configuration last electron is single but not bonded (3s1) so it is -1/2.

So,

n=3,

l=0,

Ml=0,

Ms= -1/2.
