Potassium is more reactive than sodium
Reactivity of any metal depends on its capacity to loose electrons as quickly as possible. Among Lithium, Copper and tungsten, lithium is the most reactive since it looses electrons very quickly and forms its cation. In fact, it is among the most reactive metals.
Fr; Francium
They both have 1 electron in their outer shell but because potassium has more shells, this electron is further from the nucleus. This means the outermost electron is less stronly pulled by the nucleus so it will break away easier therefore making potassium more reactive.
Sodium is more reactive than Lithium because the metals of Group 1 become more reactive as we go down the group. The ionization energy of lithium is greater than the ionization energy of sodium, and thus sodium is more reactive.
Sodium is more reactive then lithium because Na has a lower ionization energy.
which element is most reactive K Fr or Na ?
Potassium is more reactive than sodium
Potassium
Yes, potassium is more reactive than lithium, since although they both need to lose one electron to have full outer shells, potassium's outer electron is furthest from the positive attractions of the nucleus. Therefore, it is easier for potassium to lose its outer electron than it is for lithium. hope that helped

lithium is IA group element .As lithium is basic it should give its electron easily but it is not that effecient in this as sodium.As it has small radius and high nuclear attraction towards its electrons.but sodium has larger atomic radii than the lithium less nuclear attraction towards its electrons.thus sodium is more reactive than lithium.
No. Lithium is the least reactive alkali metal. Within the same environment, potassium will tarnish at a faster rate.
