here is your answer
Chemical Formula : it is a symbolic representation of a molecule of a compound.
●it tells us the elements forming a molecule.
●it indicates the number of atoms of each element present in a compound.
● it further indicates the fixed proportion by weight in which the elements are present.
BACK TO THE QUESTION :
WRITING CHEMICAL FORMULA
( CRISS CROSS METHOD )
1. the postive radical is written first with the valency at top and the negative valency is written later.
Ca2+ O2-
2.the charges present on the top are interchanged and written on the base of the element.
Ca2+ O2-
Ca2. O2
so two can cancel with each other so chemical formula withCaO
hope it helps you
