an element X has valency 3 while the element Y has valency 2.
write the formula of the compound between X and Y
999kunjal:
While writing the compound's formula, you exchange the valency and write.
here the valency of ferric thats 3 goes to oxygen, and the valency of oxygen that is 2 comes to ferric.
so ferric is element x with valency 3 and oxygen is element y with valency 2. it is just exchanged and written.
bt according to me we can't do this.
Thats how i have learnt it....ok, lets take for example water, the elements in it are hydrogen and oxygen and hydrogen has valency 1 and oxygen 2. So, while writing the compound we exchange its valencies and write it as H2O right? .....where valency of hydrogen and oxygen get replaced.
Exchanged rather than replaced
its called the criss cross method...
Criss cross method is used to make compound.

bt when this type of question is given then u can't use criss cross method .

The valencies of the elements should be exchanged and written in a compound and should also be coprime.
