Question

1) In the formation of the compound XY2, an atom X gives one electron to each Y atom. What is the nature of bonds in XY2? Give two properties of XY2.
2) An atom has two electrons more than the noble gas configuration. What type of ion will it form?​

Answer 1

Answer: 1:The bond will be chemical bond as X donates electron to Y.

2:It will form 2+ ion or say cation.

Explanation:

Answer 2

Answer:

☜☆☞ The compound formed is MgF2.

Bond formed is ionic

Properties:

1) It is a white crystalline salt.

2) The compound is transparent over a wide range of wavelength.

3) Are inert to organic chemicals and many acids.
