Divalent and Tetravalent Elements
Divalent elements are those that have a valency of 2, meaning they can form two bonds with other elements. Examples of divalent elements include calcium (Ca2+), magnesium (Mg2+), and carbon (C2+).
Tetravalent elements, on the other hand, have a valency of 4, meaning they can form four bonds with other elements. Examples of tetravalent elements include carbon (C4+), silicon (Si4+), and lead (Pb4+).
Compound formed by Divalent and Tetravalent Elements
When a divalent element combines with a tetravalent element, the resulting compound will have a ratio of 2:1 between the two elements. This is because the divalent element needs two electrons to complete its outer shell, while the tetravalent element needs four electrons to complete its outer shell.
Therefore, the compound formed by a divalent element X and a tetravalent element Y will have the formula X2Y. This means that there are two atoms of element X for every one atom of element Y in the compound.
Thus, the correct answer to the given question is option B - X2Y.
