Question

metal X loses two electrons and a non - metal Y gains one electron. Show the electron dot structure of the compound formed between them. Is it ionic or covalent? Does it have high melting point or low? Will it conduct electricity in solid state or in aqueous state? Why? Will it be soluble in water? plzz answer the question asked and plz dont give any links or references. plzz get to the point.

Answer 1

It is an ionic compound. It has high melting point. it will conduct electricity in aqueous state because movement of ions does not take place in solid state due to it's rigid structure. Ionic compounds are soluble in water but insoluble in solvents such as kerosene, petrol etc.

Answer 2

Answer:

The compound formed is ionic and it has the formula XY₂

Explanation:

• Since metal X loses 2 electrons and non-metal Y gains 1 electron, there have to be 2 Y atoms to gain the 2 electrons lost by X
• The compound formed from X and Y is an ionic compound
• Since it is an ionic compound, there are strong electrostatic forces of attraction and it will be difficult to break these forces
• Thus, the compound has a high melting point
• The compound will conduct electricity in an aqueous state
• In an aqueous state, the X and Y will dissociate from their crystalline structure and form ions and free electrons which can conduct electricity
• The compound is soluble in water as it is ionic

The compound made from X and Y elements is ionic.
