Question

exchange of valences​

Answer 1

Answer:

Exchanging valency method is to make it easy to understand. ... Valency of an element is a measure of the combining capacity of its atom to form chemical bonds. Valency or Valence: Valency is defined as the number of hydrogen or chlorine atoms with which 1 atom of the element would combine.

Answer 2

When atoms of one element combine with the atoms of another element to form formula units, they do so in fixed numbers depending upon the capacities of the atoms to form bonds.

Valency of an element is a measure of the combining capacity of its atom to form chemical bonds.

Valency or Valence:

Valency is defined as the number of hydrogen or chlorine atoms with which 1 atom of the element would combine.

As a general rule, if an atom participates in ionic bonding, the valency tells the charge on the ion formed. If the atom participates in covalent bonding, the valency tells the number of electrons the atom shares with its partner atom(s).

I think exchanging valencies came into your mind after studying criss cross method but i must tell you valencies are never exchanged . It simply tells us the no. of electrons gained or lost to attain the stable structure of nearest noble gas configuration.
