Step 1

Here we need to learn how to name Ionic and Covalent compounds.

Ionic compounds: These are the compounds formed by the combination of Metal and Nonmetals.

Covalent compounds: These are compounds formed by the combination of Non-metals.

Step 2

General rules for ionic compounds nomenclature:

Rule 1

Consider the periodic table for the position of cations and anions

Metals are placed on the left side of the periodic table which results in cations by losing electrons. Anions are generated by the non-metals after gaining of electrons which are placed in 15, 16, and 17 groups of the periodic table.

Rule 2

Write down the chemical formula for the Ionic compound.

Let’s say we have Na+1 as Cation and Cl-1 as Anion.


The chemical formula will be NaCl.

Rule 3

Write the name of metal first.

Here the metal is Na i.e. Sodium

So, Sodium is to be written first while naming this ionic compound.

Rule 4

Write the name of Anion and put “-ide” in the ending.

Here the anion is Chlorine. And it should be named as Chloride (see ide in the end)

Rule 5

Combine both cations and anions name.

So, the proper nomenclature of NaCl come out to be Sodium Chloride.

Step 3

Now, these rules are valid for all...
