They show the types of molecules that make up an atom

They show the elements of make up a compound

They show the 3 dimensional shape of a molecule

They show the types of atoms that make up a molecule

They should the number of each type of atom in a molecule

Answer 1

• They show the elements of make up a compound
• They show the types of atoms that make up a molecule
• They show the number of each type of atom in a molecule

Step-by-step explanation:

To answer this question we need to know what is a compound.

• A compound is a substance that is made by two or more atoms of different elements that are chemically combined.
• A chemical formula of a compound is a formula that shows the elements that make up a compound and also the types of atoms that make up the molecule.
• Additionally, the chemical formula shows the number of each type of atom in a molecule.
• In this case, the chemical formula of a molecule of H₂O shows that it is made up of one hydrogen atom and two oxygen atoms.
