If you were to remove an electron from a sodium atom that has eleven protons, what would be the electrical charge of the ion?

positive one (+1)

Explanation:

sodium having atomic mass is twenty three (23) and atomic number is eleven (11).

Sodium atom having only one electron in it's outer most shell and it is easy for atom to lose this electron from outer most shell to make itself stable.

So after losing this electron positive charge on the upper right side of the atom will occur with the number of electron lose that is Na+1 .

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
