Question

4) an atom x has three electrons more than the noble gas configuration. What type of ion will it form? Write the formula of its (i) sulphate (ii) nitrate (iii) phosphate (iv) carbonate (v) hydroxide.

Answer 1

$\underline{\underline{\huge\mathfrak{ANSWER}}}$

Let the atom be $\mathbf{x}$


The Ion formed by Atom will be $\mathbf{X^{3+}}$
____________________________________

The Formula of Compounds when X combines with :

1) $\mathsf{Sulphate}$

$\mathsf{X^{3+} + SO^{2-}_{4}}$

$\textsf{Interchanging the Valencies}$

$\mathbf{X_{2} (SO_4)_3}$

=========================================

2) $\mathsf{Nitrate}$

$\mathsf{X^{3+} + NO^{-}_{3}}$

$\textsf{Interchanging the Valencies}$

$\mathbf{X(NO_3)_3}$

=========================================

3) $\mathsf{Phosphate}$

$\mathsf{X^{3+} + PO^{3-}_{4}}$

$\mathsf{Interchanging the Valencies}$

$\textsf{Valencies are cancelled, since both have same valencies}$

$\mathbf{XPO_4}$

=========================================


4) $\mathsf{Carbonate}$

$\mathsf{X^{3+} + CO^{2-}_{3}}$

$\textsf{Interchanging the Valencies}$

$\mathbf{X_2 (CO_3)_2}$

=========================================

5) $\mathsf{Hydroxide}$

$\mathsf{X^{3+} + OH{-}}$

$\textsf{Interchanging the Valencies}$

$\mathbf{XOH_3}$

=========================================

Answer 2

It will form a cation (+ve ion).

Explanation:

• For attaining noble gas configuration, it will loose 3 electrons. Then, it will form a cation (positive ion) and its valency is 3.
