A substance has a higher temperature when its particles have a higher average kinetic energy. Imagine two different substances that are both pure, meaning they each contain only one type of matter. Each substance has a different temperature. Which two properties determine which substance has the higher temperature?

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!
