The most common cation in the interstitial fluid is sodium at 150 mM. Next is calcium at 8.4 mM and potassium at 5 mM.
Sodium.
A cation is a postitve ion. Sodium (Na+) is a postitive ion. Therefore, Na+ is a cation. It's definitional.
Salts made of a metal and a nonmetal are named this way: [metal] [nonmetal root]-ide Examples: sodium + chlorine = sodium chloride potassium + iodine = potassium iodide Salts made from a metal or other complex cation and a nonmetal or other complex anion are named based on the cation and anion names: ------------------------------- ammonium ion + hydroxide ion = ammonium hydroxide sodium ion + hypochlorite ion = sodium hypochlorite calcium ion + chloride ion = calcium chloride
The sodium cation is Na+. The valence of sodium is +1.
calcium ; sodium
Soft water contains sodium(cation). Sodium is highly water soluble and this makes water soft.
The cation is the sodium ion Na+.
Sodium is easier to form Na+ then Calcium forming Ca2+. The main reason is because Sodium has got 1 valence electron, which is more unstable than Calcium having 2 valence electrons. It requires less energy to remove one electron from Sodium than two electrons from Calcium. Therefore, Sodium is higher than Calcium in the reactivity series.

Sodium is the primary cation for ECF, potassium is the primary cation for ICF.
The cation, or positively charged ion, in NaCl is Na+.
The Chief Extracellular cation is sodium.
CATION: Na+ ANION: F-
Any element that ionises electrons is a cation. e.g. Sodium (Na) is the elemental atom Na^(+) is the sodium cation.
