Is oxyden molecule a polar or non polar covalent? why?

Diatomic oxygen is made up of the same two elements, and they equally share the 4 electrons that make up the double bond between them. They're equally electronegative, which means that there are not any partial charges for each element. Since neither atom pulls harder, it's a non-polar covalent bond.

Explanation:

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.
