An atom is what makes up chemical formulae. Just look at the Periodic Table -- those are your chemical formulae for atoms. Can be from H to Uuo.
The diatomic chemical formula of chlorine is Cl2.
There is one atom of that element in the molecule.
Yes, it is true. Example: NaCl; 1 atom of sodium, 1 atom of chlorine.
If you think to XeF4, this is the chemical formula of xenon tetrafluoride.
Water is a chemical compound because it has 2 hydrogen atoms and 1 oxygen atom. if there is a formula for water it means water is a chemical in other words H2O
Each chemical element has a standardized chemical symbol, not a formula.
The subscript in a chemical formula represents the amount of that atom in that compound's formula.
H2O. It is the formula of water.
H
Cl.
NH3
The chemical symbol (not formula) of fluorine atom is F; the molecule is F2.
The diatomic chemical formula of chlorine is Cl2.
There is one atom of that element in the molecule.
CO
A chemical symbol represents a single atom of an element, but a formula represents a chemical entity with constant composition that contains at least two atoms.A chemical symbol represents a single atom of a chemical element, but a chemical formula represents the types and numbers of atoms in a chemical entity larger than a single atom. The entity is called a molecule if the compound is covalently bonded and a formula unit if the entity is ionically bonded.
