Not sure if it's number one, but NaCl is all over the place; that makes Cl-a big one.
The chief intracellular cation in the human body is the potassium ion. On the other hand, the primary extracellular cation is the sodium ion. In is the actions of these ions that allow neurons to transmit electrical impulses.

Major Intracellular cation - K+ (Potassium) Major Extracellular cation - Na+ (Sodium) Major Intracellular anion - PO4+ (Phosphate) Major Extracellular anion - Cl- (Chloride)
No, it is potassium.
The electrolyte with the highest intracellular concentration would probably be considered to be sodium chloride (NaCl), or at least Na^+ cation.

In the process of intracellular digestion, lysosomes are the main organelles. Lysosomes contain enzymes that are made by cells, and their primary function is to digest things.

The cation silver is a poison, not an essential body nutrient. Hope this helps :)
