WebGive the number of neutrons in each naturally occurring isotope of argon: argon-36, argon-38, argon-40. 22,24,26. Write the symbols for the following isotopes: a)6 protons, 8 … WebWhen a stable atom gains or loses an electron, it becomes an ion. For example, when chlorine takes an electron from sodium, and sodium gives that electron to chlorine, they become ions and form NaCl. Sodum is a cation (lost an electron and became positive) and chlorine is an anion (gained an electron and becomes negative) in this situation.
