Expert Answer
TO make chemical formula we must have symbol of elements and valency of elements of given compounds ,then by cross multiplication of valency, we can find the chemical formula.
for example ,the chemical formula of sodium chloride is NaCl.
here the symbol and vaenlcy of sodium is Na and +1 respectively and the symbol and valency of chlorine is Cland -1 respectively .
