Which of the following is the greatest dissolved solid in ocean water? magnesium chloride plankton sodium chloride calium

The right answer is Sodium chloride.

Sodium chloride is a chemical compound whose formula is NaCl. Everyone knows the taste because it is, more simply, table salt.

Let's take a pool 50 meters long and 15 meters wide and fill it with sea water. Then let's go to his analysis. We find:

1400 tons of pure water

50 tons of sodium chloride

2 tons of magnesium

1 ton of sulfur

And then much less frequent elements

explanation:

metals have excess of electrons whereas non-metals have deficiency of electrons. thus, in order to gain stability metals easily donate their electrons to the non-metals.

for example, electronic configuration of sodium is and electronic configuration of phosphorous is .

when a phosphorous atom and sodium atom combine together then sodium will donate is extra one electron to the phosphorous atom. as a result there will be formation of ionic bond between sodium and phosphorous.

the reaction will be as follows.

there, are three sodium sodium atoms and each of them will donate its one extra electron to phosphorous atom. thus, the sub-shell of phosphorous gets completely filled.  

thus, we can conclude that electrons are transferred from atoms of sodium to atoms of phosphorous. this transfer makes the sodium atoms donate one electron and the phosphorous atoms to gain one electron. as a result, the sodium and phosphorus atoms strongly attract each other.

i think   the answer is c hope i'm right
