Place these waves in order from shortest wavelength to longest. sound waves, light waves, ocean waves

Ocean waves aren't technically related to this. Sound waves are shorter than

light waves, depending on the type of light wave.

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: )
