H2O, Na, Ca, Cu, Fe and K.
Blood contain - as traces - organic salts of metals (Na, Fe, Cu, Zn etc.).
Any metal that is more reactive than copper (Cu) will react with copper acetate in a singe replacement reaction. These would be such metals as Li, Na, K, Ca, Mg, Al, An, Cr, Fe, Cd, Co, Ni, Sn, Pb, and some others as well.
Spinach's main elemental components are carbon, hydrogen and oxygen. As far as trace components a study of the chemical composition, the minerals K, Ca, Mg, Na, Fe, Zn, Cu and P were present.
Bioinorganic elements are H, O, N, C, Na, P, S, Cl, K, Ca, Fe, Mn, Cr, Co, Cu, Zn, Se, I; not still confirmed role: B, Ge, V, Si.
Non-metals such as carbon are insulators of heat.

Sodium (Na) is least likely to be reduced. It is very easily oxidized as it will lose its valence electron with little difficulty.
Blood contain - as traces - organic salts of metals (Na, Fe, Cu, Zn etc.).
These symbols are the standardized symbols for chemical elements: some examples are Na, K, Li, Ca, Mg, Th, Cu, Fe etc.
Macronutrients are proteins, fats, carbohydrates; micronutrients are Na, Ca, P, K, Fe, Cu, Ni, Se, Mg, N, etc.
No, sodium (Na) is a conductor not a semi conductor
