Difference Between Sodium and Potassium | Compare the

May 19, 2011· Sodium and Potassium are naturally occurring alkaline metals that show many similarities in their behaviors. Both sodium and potassium ions are essential for all life forms. Both ions are highly reactive and easily dissolve in water which is why both are found more in seawater than on land. Both sodium and potassium are also found as parts of various minerals.

WebElements Periodic Table » Potassium » reactions of elements

The reaction is slower than that of rubidium (immediately below potassium in the periodic table), but faster than that of sodium (immediately above potassium in the periodic table). 2K(s) + 2H 2 O → 2KOH(aq) + H 2 (g) Reaction of potassium with the halogens. Potassium metal reacts vigorously with all the halogens to form potassium halides.

What Makes Metals So Marvelous? - inChemistry

Oct 08, 2019· Metals react. Just because metals are really flexible doesn’t mean they aren’t reactive. Elements on the left-hand side of the periodic table prefer to give up their electrons, to form ionic compounds. Pure lithium, sodium, potassium, and other Group 1 metals are so reactive they are stored away from air or water.
