Question

An element X of atomic number 12 combines with an element Y of atomic number 17 to form a compound XY2. State the nature of chemical bond in XY2 and show how the electron configurations of X and Y change in the formation of this compound.

Answer 1

Explanation:

• When the element X of atomic number 12 combines with an element Y of atomic number 12, it forms a compound XY2 with ionic bonds. This happens when electrons from atoms of element X transfers to element Y.
• Every atom of element X has 12 electrons having an electronic configuration of 2, 8,2, donates its 2 electrons to produce X2+ ion that posses an electronic configuration of 2, 8 to determine the compound XY2. Similarly, Each atom of element Y has 17 electrons having an electronic configuration of 2,8,7, completes the octet by gaining 1 electron to form Y-  ion having an electronic configuration of 2,8,8.
