Why pottasium with atomic number 19 is more reactive than lithium with atomic number 3?

potasium has larger atomic radius so loses electrons more readily. All alkali metals are very reactive, but each one is slightly more reactive than the one directly above it in the Periodic Table. Tha larger the atomic radius the weaker the attractive force will be so the electrons farther from the nucleus are lost more easily during the reaction.

What is the proton number of the element lithuim?
Lithium has an atomic number of 3.Lithium's atomic mass is 6.9.The atomic number refers to the number of protons in the nucleus of an element. As elements are electronically neutral the atomic number also refers to the number of electrons in a normal atom of that element.The atomic mass is an average and can be said to refer to the combined mass of the protons and neutrons in the nucleus (protons and neutrons both having an atomic mass of 1).Lithium, therefore, has 3 protons, 3 electrons and 4 neutrons (on average).Lithium is in group 1 which means it is an alkali metal.Being in group 1 also means that Lithium has only one electron in its outer shell.Alkali metals are highly reactive because they only need to get rid of one electron in an ionic bond in order to have a full outer shell. As one travels down the periodic table the number of electron shells increase and so too does the distance an outer electron is from the nucleus. This increase in distance means the nucleus' hold on the outer electrons is diminished and thus the element will give up its outer electrons easier. This, in turn makes the alkali metals further down the table more reactive than those higher up.Alkali metals are so called because when they react with water they form an alkali. Lithium reacting with water will form lithium hydroxide.Lithium is a metal with a relatively low density that floats on water and will react violently with water and discolour rapidly in air.
