Question

Reaction between x and y forms compound Z. X loses electron and y gains electrons.Which of the following properties is not shown by Z?

Answer 1

Answer:

here irs ur answer please mark me brainliest

Explanation:

Given that the compound  X and Y form compound Z.

Here, X loses electron and Y gains electron meaning that an ionic or an electrovalent bond is formed. Thus, the compound Z is a crystalline solid, has high melting and boiling point. It conducts electricity in the molten state. 

The compound Z cannot have a low melting point.

Answer 2

Answer:

has low melting point

Explanation:

X is an electropositive metal as it loses electron and Y is a non-metal as it gain electron. Compound formed between metal and nonmetal is an ionic compound.

Ionic compounds are solids, good conductor in the molten state and have high melting point
