Answer 1

Explanation:

Cations are the positive ions formed by the loss of one or more electrons. It has one valence electron in the third principal energy level. ... Upon losing that electron, the sodium ion now has an octet of electrons from the second principal energy level.

A sodium atom has one electron in the outer shell. A chlorine atom seven electrons in the outer shell. A sodium atom loses an electron to a chlorine atom. The sodium atom becomes a positive sodium ion.

Answer 2

Answer:

1. atom or molecule that have lost 1 or more electrons is an ion.
