Question

An atom B has two electrons more than the nearest noble gas configuration. State the type of ion which will be formed by B and also write the formula for the following with respect to B.

Formula of sulphate of B
Formula of Phosphate of B
Formula of Carbonate of B
Formula of Nitrate of B

Answer 1

Answer:

Hey How are you ??

Explanation:

Since it is given that B has 2 electrons more than the nearest noble gas.

This means for attaining noble gas configuration it should loose 2 electrons.

Hence it will form a positive ion with +2 valency

and can be written as B+2.

Formula of Sulphate.

B(SO4)

Formula of phosphate:

B3(PO4)2

Formula of carbonate:

B(CO3)

Formula of Nitrate:

B(NO3)2
