Answer:
Chemical formula.
Explanation:
A chemical formula have fix proportion of atoms of elements.
Chemical formula:
A chemical formula is the way of presenting the chemical proportion of atoms of those elements, that combine to form a compound.
For example:
Water consist of two atom of hydrogen and one atom of oxygen. The atoms of both elements combine to form a compound i.e water. The atoms of both elements always combine in a fixed ratio which is 2:1 in molecule of water.
H₂O
2:1
Carbon dioxide consist of two atom of oxygen and one atom of carbon. The atoms of both elements combine to form a compound i.e carbon dioxide. The atoms of both elements always combine in a fixed ratio which is 1:2 in molecule of carbon dioxide .
CO₂
1;2
