Element X reacts with element Y to give a product containing X2+ ions and Y- ions. (a) Is element X likely to be a metal or a nonmetal? Explain. (b) Is element Y likely to be a metal or a nonmetal? Explain. (c) In what groups of the periodic table are elements X and Y likely to be found?

Verified step by step guidance

1. Step 1: Consider the nature of X2+ ions. Since X forms X2+ ions, it loses electrons to form a positive charge. Elements that lose electrons to form cations are typically metals.
2. Step 2: Consider the nature of Y- ions. Since Y forms Y- ions, it gains electrons to form a negative charge. Elements that gain electrons to form anions are typically nonmetals.
3. Step 3: Determine the likely group for element X. Metals that form 2+ cations are often found in Group 2 of the periodic table, known as the alkaline earth metals.
4. Step 4: Determine the likely group for element Y. Nonmetals that form 1- anions are often found in Group 17 of the periodic table, known as the halogens.
5. Step 5: Summarize the findings. Element X is likely a metal from Group 2, and element Y is likely a nonmetal from Group 17.
