Question

does Na+ have same nuclear charge as Na?

Answer 1

Answer:

Bonjour mate...

Yes Na+ is smaller than Na because Na+ is formed when an electron is lost from the Na atom,Thus the effective nuclear charge increases bcz the number of protons exceeds the number of electrons . This results in bringing the valence shell a little closer to the nucleus because of a very strong nuclear pull.

Answer 2

Answer:

Na+ has a positive charge i.e. it has 10 electrons

and 11 protons.

Na is an atom and atom is neutral i.e. it has 11 electrons and 11 protons. It doesn't carry any charge.
