WebIons: Atoms contain the negatively charged subatomic particles called electrons which are found outside the nucleus. These particles can be lost or gained by an atom. When electrons are lost, the atom becomes positively charged and is called a cation. When electrons are gained, the atoms becomes negatively charged and is called an anion. Web1 feb. 2024 · Thus, magnesium has two valence electrons. Valency of Magnesium (Mg) There are many different ways to find out the valency of an atom which reflects the ability of an atom to bond with other atoms. Valence describes how easily an atom or a free radical can combine with other chemical species.
