Formula of the Compound

The formula of a compound is determined by the combination of the atoms involved. In this case, atom X has 7 valence electrons while atom Y has 2 valence electrons. To form a stable compound, both atoms will undergo a chemical reaction where they will share or transfer electrons.

Since atom X has 7 valence electrons, it will require one more electron to achieve a stable configuration. On the other hand, atom Y has 2 valence electrons and needs to gain or lose 6 electrons to attain stability.

Considering the electronegativity difference between the two atoms, it is likely that atom X will donate its extra electron to atom Y, resulting in the formation of an ionic bond.

Type of Bond Formed

An ionic bond is a type of chemical bond that forms between atoms with a significant difference in electronegativity. In this case, atom X is likely to donate one electron to atom Y, resulting in the formation of an ionic bond.

Ionic bonds occur between a metal and a non-metal, where the metal atom loses electrons and becomes a positively charged cation, while the non-metal atom gains electrons and becomes a negatively charged anion. The electrostatic attraction between the oppositely charged ions holds the compound together.

In this compound, atom X donates one electron to atom Y. Atom X becomes a cation with a positive charge because it loses an electron, while atom Y becomes an anion with a negative charge because it gains an electron. The charges on the ions will depend on the specific atoms involved.

Final Compound

Based on the valence electrons and the type of bond formed, the compound formed between atom X and Y can be represented as XY.

However, it is important to note that without specific information about the atoms involved, it is not possible to determine the exact compound name or the charges on the ions. The specific elements and their charges need to be known to provide a more accurate formula.

In summary, the compound formed between atom X and Y is likely to be an ionic compound, with atom X donating one electron to atom Y. The resulting compound can be represented as XY, but the specific charges and names of the elements will depend on the specific atoms involved.
