PLZ HELP! WILL GIVE BRAINLIEST, 5 STARS, AND A THANKS!! How do the types and numbers of atoms that repeat to make up a substance affect its properties?

Chemical formula determines chemical structure and the properties of a substance.

Explanation:

A substance's chemical formula depicts what atoms are in the substance, how many times they reoccur, and in what ratio. Chemical formulas can be empirical, molecular, or structural in nature.

All of these factors affect a substance's properties, such as isomers of a compound.

Explanation:

The chemical formula of a substance depicts what atoms are in the substance, how many times they reoccur and in what ratio. Chemical formulas could be in form of: empirical, molecular or structural formula.

All of these determine the property of the substance, for instance in isomers of a compound.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
