Question

What is difference between Na and Na+ in terms of number of electrons​

Answer 1

Answer:

Na means, there are 11 electeons in the valency shell and it will not be stable.

If it loses one electron, to get stabled electronic configiration of Ne. So in this earth añd atmosphere there are so many elements those are trying to loosing and gaining of electeons to get stable,by the process of some chemical reaction.

Hope this heps you

Answer 2

Answer:

Na has 11 electrons in total and, Na+ has 10 electrons.

Explanation:

Na is the symbol for an atom of Sodium.

Sodium's atomic number is 11.

This means that it's number of protons is 11.

Since it an atom (not an ion), the number of protons is equal to the number of electrons.

So, it has 11 electrons.

Na+ is an ion of Sodium. Sodium's atomic number is 11.

So, its electronic configuration will be

K    L     M    N

2    8     1      -

When an atom of sodium looses an electron to become stable, it forms a sodium ion.

Therefore, an ion of sodium Na+ has 11 - 1 = 10 electrons.
