An element x is divalent. An element Y is tetravalent. write down the ...
Compound Formula: X2Y4
Explanation:
Divalent Element X:
Divalent elements have a valency of 2, which means they can form two chemical bonds with other elements. In this case, the element X is divalent, so it has a valency of 2.
Tetravalent Element Y:
Tetravalent elements have a valency of 4, which means they can form four chemical bonds with other elements. In this case, the element Y is tetravalent, so it has a valency of 4.
Formation of the Compound:
When divalent element X combines with tetravalent element Y, they will form a compound. The formula for the compound can be determined by balancing the valencies of the elements.
Since element X is divalent and element Y is tetravalent, we need to find the least common multiple of their valencies, which is 4. This means that each X atom will form 2 bonds, and each Y atom will form 4 bonds.
To balance the valencies, we need to have 2 X atoms for every 1 Y atom. This is because 2 X atoms will contribute a total of 4 bonds (2 x 2 = 4), which can be satisfied by 1 Y atom.
Therefore, the formula of the compound formed by these two elements is X2Y4. This means that two X atoms will combine with one Y atom to form the compound.
Summary:
- Element X is divalent and has a valency of 2.
- Element Y is tetravalent and has a valency of 4.
- The compound formed by these elements has the formula X2Y4.
- The formula indicates that two X atoms combine with one Y atom to form the compound.
