Question

An atom X has two electrons more than its nearest noble gas. What type of ion will it form and represent it. Write the formula of its sulphate ,nitrate and phosphate

Answer 1

Answer:

It will form an electropositiveion sine it has three electron in itsouter most shell. And therefore it hasvalency 3+ .

Answer 2

Explanation:

Given -

• An atom X has two electrons more than its nearest noble gas.

To Find -

1. What type of ion will it from
2. Write the formula of its sulphate, nitrate and phosphate.

Solution -

If Atom X has 2 electron more than its nearest Noble gas.

Then, It's Valency is 2 and it belongs to Group 2 (Alkaline Earth metal).

And It will form Cation.

Formula of Sulphate = XSO4

Formula of Nitrate = X(NO3)2

Formula of Phosphate = X3(PO4)2
