The clownfish is a species of fish that lives between the stinging tentacles of sea anemones. the clownfish protects the anemone from anemone eating fish, while the anemone’s tentacles protect the clownfish from predators. the relationship between clownfish and anemone is an example of
a) commensalism.
b) competition.
c) mutualism.
d) parasitism.

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!
