Question

How we will find the valency of any chemical formula?

I have to how can we get the chemical formula by chemical name?
example :-- barium bromide

Don't copy from anywhere. I want to know your own way of doing it. If you don't know then don't answer .

Answer 1

valency is the combining power of elements that is when elements combined some may take or give the extra to fill the gap the index numbers that is safe for hydrogen its one in the first shell so it gives its electron.

chemical formula is written by if for example its HCL that is HCL the valency of hydrogen is 1 and chlorine is also won the elements just exchange the Valency number.

you will have to learn the atomic number of all the elements which you want so you can find its valency and write it and just write it by exchanging ok and another example and giving let it be hydrogen sulphate H2S the valency it's given ok hydrogen has won and sulphide adds to the valency of sulphide is given to hydrogen and hydrogen is given to sulphate that its becomes ets2 and SP comes as itself so easy if H2S that is hydrogen sulphide
