Ca - your body contains about ikg of it; its the most abundant METAL the body as it makes up your bones, also needed as a second messegner in cell transduction.
He- helium, unreactive nobel gas, lighter than air; dont think so!
Na & K - important ions in plasma and body fluids, very important for many functions but dont make up as much as the C,H,N,O
Ni; Nickel: nope!
