Answer 2

Answer:

Hydrated ions are the state of potassium and sodium in the human organism.

Explanation:

$K^{+}$ is a monoatomic monocation, an alkali metal cation, elemental potassium, a monovalent inorganic cation, and an alkali metal cation. Inside animal cells, potassium is the most abundant cation (positive ion), but sodium is the most abundant cation outside of animal cells.
