Answer:

Sometimes, because of different conditions under which a chemical reaction takes place, the valency of the same element changes. Thus metals like lead, tin, copper, mercury, iron etc exhibit variable valency. Normally, the metals donate electrons from their valence shell, so as to form positively charged ions.
