have 8 electrons ..

form ionic bond

Answer 2

Answer:

The expected formula of the compound is XY.

Explanation:

• It is given that X has two electrons and Y has six electrons in their outermost shells.
• Since X has 2 valence electrons, it will lose these two electrons to complete its octet.
• After losing the two electrons, element X will form an anion, i.e., X²⁻.
• Y has 6 valence electrons. It will accept two electrons to complete its octet.
• After gaining two electrons, element Y will form a cation, i.e., Y²⁺.

Therefore, the formula of the compound formed will be XY.
