How marly electrons are in an atom of elemental

sodium?

The sodium atom is left with a full outermost electron shell with eight electrons, and the outermost shell of the other atom is full as well.

Explanation:

The sodium atom now has a positive electrical charge of plus 1, and the other atom has a negative charge of minus 1. The two opposite charges attract, and the two atoms now form the molecule of a compound.

Answer: 11 Electrons

Explanation:

We know that the atomic number of sodium is 11. This tells us that sodium has 11 protons and because it is neutral it has 11 electrons.
