•Writing a chemical formula,
We know that each atom of an element has a symbol. These symbols are used while writing a chemical formula. Their combining capacitices (valency) also play a major role in determining the chemical formula of a compound
Let us clarify it better using an example,
Take common salt which is Sodium Chloride.
Na is the symbol of Sodium and Cl is the symbol of Chloride
Both have a valency of 1
On crossing them,
We get NaCl
Thus,verified
relationship relationship expressed by symbols in chemistry is known as chemical formula.....
you can take an example of very easy hydrogen and oxygen by which means hydrogen ''H"and 2 molecules and oxygen "O"
H^2 O
=} H2O
which means chemical formula of water......
therefore answer is veried.........
