Question

how do atoms attain noble gas configuration write the formula of its x sulphate​

Answer 1

Explanation:

X has three electrons more than noble gas configuration 

so,it will form X3-         

formula with sulphate is X₂(SO4)₃

nitrate  is X(NO3)₃

phosphate is XPO4

Carbonate is X₂(CO3)₃

hydroxide is

Explanation :

According to the question, An atom 'x' has three electrons more than the noble gas configuration. For attaining the stable electronic configuration or noble gas configuration, it will loose 3 extra electrons.

So, it will form a cation (positive ion) and its valency will be, 3.

The valency of the following anion will be,

Valency of Sulphate (SO_4) = 2

Valency of Nitrate (NO_3) = 1

Valency of Phosphate (PO_4) = 3

Valency of Carbonate (CO_3) = 2

Valency of Hydroxide (OH) = 1

Thus, the formula of the compounds will be,

X_2(SO_4)_3\\\\X(NO_3)_3\\\\X(PO_4)\\\\X_2(CO_3)_3\\\\X(OH)_3
