Answer 1

Answer:

magnesium has a valency of 2

and an oxidation state of 2+

Answer 2

$\LARGE\underline{\sf{\red{Required\:answer:-}}}$

Valency : Valency is defined as the combinin capacity of an element (or) the number of electrons shared (or) transfered from one atom to another atom. Valency is always a whole number.

Magnesium has 12 electrons.The arrangement of these 12 electrons i.e , the electronic configuration of magnesium is 1s² 2s² 2p⁶ 3s². The number of electrons in the valence shell (or) the number of valence electrons in magnesium are 2. Magnesium tries to transfer these two electrons to attain stable electronic configuration. Hence , The valency of Magnesium is 2.
