Zinc (Zn) does not have variable valency
Yes elements with variable valency can be stored in water. example Phosphorus.
Manganese is a transition element and has a variable valency but generally has a valency of 2 and exists as Mn2+
The valency of tin is variable. It can either be 2 or 4.
the valence of gold is 3+

The valency of tin is variable. It can either be 2 or 4.
Variable valencies are the valencies which can change e.g. Fe (iron) can either have the valency of 2 (Fe II) or 3 (Fe III)
the valence of gold is 3+
yo dawg i heard you like exhibits so we put xzibit in yo exhibit so you can lookat xzibit while you exhibit xzibit in yo exhibit
it does. for example in H2O oxygen has a valency 2 while in hydrogen peroxide H2O2 oxygen exhibits valency 1
Certain elements combine with other atoms, donating, accepting or sharing electrons in different proportions depending on the nature of the reaction. For example, iron combines with oxygen to form ferrous oxide as well as ferric oxide. In the formation of ferrous oxide, iron exhibits a valency of +2, whereas in ferric oxide, it has a valency of +3. This is termed variable valency
1 or 3

Iron has variable valence. It can be either 2 or 3.
