4. How is salinity affected?

Three major factors influence salinity (salt concentration) in Pacific Ocean waters: precipitation, evaporation and winds. Precipitation brings freshwater into the ocean, diluting its salt concentration.

"the periodic table is arranged in order of atomic number."

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: )
