Hey mate,...

Use the below steps :-

↪Write the symbols side by side, basic radical is written first and then acidic radical.

↪Write the valency of each atom on top of its symbol.

Hope it will help you.

Sai.

↪Divide the valency numbers by their highest factor, if any, to get the simple ratio. Ignore the (+) or (-) symbols of the radicals. Interchange the valencies of the radicals.

↪Write the interchanged valency numbers to the lower right of the radicals. If the radical is a group of atoms and has a valency number more than 1, enclose it within brackets.

To find the valency of an element, it is absolute that we must know the atomic number of that element.

For example, for the element Carbon ⚛️
the atomic number is 6
Convert into electronic configuration:. 2, 4

Consider the final shell alone.
Here 4️⃣ so Subtract 4 from 8️⃣
the answer is 4.

Thus, the Valency is 4

For elements with valence electrons 4 and <4 the Valency is the valence number itself. For example Lithium ⚛️ the valence shell is 1. So Valency is 1️⃣

For elements with valence electrons >4, subtract it from number 8. For example Fluorine ⚛️ the Valency is 2,7 and the valence shell numner is 7. Subtracting from 8 we get 1. so Valency is 1️⃣.

For elements in the Oxygen group, it is not the same. For example Oxygen has 2,6 . But the valence can be 6 or 2 according to the situation.

☺Hope you understood☺
