What is the most abundant metal in sea water
I suspect Mg ion
a google search turned up data showing that Na is about 8 times the concentration of Mg. (by mass)
So, since Na is lighter than Mg, it would be even more abundant, counting the number of atoms present.
I sort of consider NaCl as defining salt water :)
Hmm. Hadn't considered that take on it. You may be right...
