Explanation:

Gases and liquids take the shape of the container.

A gas fills all available space.

A solid maintains its shape.

A liquid can be poured.

A gas is compressible.

A liquid and solid have fixed volumes.

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!
