Element x has an electron configuration of 2-8-3. this element will combine with the phosphate ion to form a compound with the formula

The electron configuration is the distribution of electrons in the atomic or molecular orbitals of an atom or molecule.

The compound that is formed is

A core phosphorus atom is surrounded by four oxygen atoms in a tetrahedral arrangement in the phosphate ion, which has a molar mass of 94.97 g/mol.

The formula of a phosphate ion is

It has a molar mass of 94.97 g/mol. In a tetrahedral structure, one core phosphorus atom is surrounded by four oxygen atoms.

The formal charge of the phosphate ion is -3 which means the ion has to gain 3 electrons to get neutral.

Now,

As given, X has an electronic configuration of 2-8-3. According to the electron, configuration, X has a valency of 3 (number of electrons in the outermost electron shell). As a result, X has been classified as a group  3 elements.

With a valency of 3, X is able to lose or gain its 3 electrons to form a bond.

The formal charges are in equilibrium (3 - 3 = 0). This means that X's total number of electrons lost equals the phosphate ion's total number of electrons received.

Thus, this means that the compound is .

Explanation:

First off, what is the chemical formula of the phosphate ion?

The formula of a phosphate ion is given as; (PO4)3−

The phosphate ion is a polyatomic ion with the empirical formula (PO4)3−

and a molar mass of 94.97 g/mol. It consists of one central phosphorus atom surrounded by four oxygen atoms in a tetrahedral arrangement. The phosphate ion carries a −3 formal charge.

With a formal charge of -3, it means the ion would have to gain 3 electrons when entering into a bond in order for it to be neutral.

X on the other hand as an electronic configuration of 2-8-3. The electron configuration reveals X has a valency (Number of electrons in the outermost electron shell) of 3. As such, X is a group 3 element (Aluminium to be much precise).

With valency of 3 it means X is willing and able to lose its 3 electrons to enter into a bond.

This leads to the formular between X and the phosphate ion to be . XPO4

The formal charges balances each other (3 - 3 = 0). This means the total number of electrons lost by X is the total number of electrons received by the phosphate ion.
