Yes, very. <- This does not answer the question appropriately.
Potassium has the largest atomic radius.
Na^+ is called a sodium cation.
The Na+ you are referring to is a sodium ion.
4Na + O2 = 2Na2O The reactants are the sodium (Na) and the oxygen (O2) NB The product is Na2O
Sodiumchloride is dissociated in water: NaCl-------Na+ + Cl-
Na+ and Cl- are spectator ions.
Na+is bigger
Na+-K+ ATPase
Na+H2o+H2=2 Nhoh
Na+ plus OH- plus H+ equals H2O plus Na+ plus Cl-
NA
Na cl2
Na+ does not affect pH.
Na2S
