Definitely lithium. Lithium is a Group I alkali metal, while Beryllium is a Group II alkaline earth metal and are on the same period. Group I Alkali metals are generally more reactive as they only need to lose one electron to have a complete outer shell.

∙ 13y agopottasium. it has the most energy levels therefore there is less attraction between the nucleus and the valence electrons therefore the valence electrons are lost easier making it more reactive. reactivity increases up to down on the Periodic Table.

∙ 13y agoThe ionization energy of lithium is greater than the ionization energy of potassium, and potassium is consequently more reactive.

∙ 15y agoLithium as it is an alkaline metal. However Barium being an alkaline earth has the greater total reactant energy.

What order of reactivity NOT activity are the metals Barium Lithium Radium and Sodium in?
The metals listed are all alkali metals or alkali-earth metals. The periodic trend for these groups is: as you move down the group/family, reactivity increases. The alkali metals will be more reactive than the respective alkali-earth metals.Sodium and lithium are alkali metals, so you can organize them first. Sodium is further down in the family than lithium, so we can say that sodium is the most reactive out of the group, followed by lithium. Then we have barium and radium left. Radium is slightly more reactive than barium due to its position, so it is third and barium is fourth.
Which is more reactive lithium in group 1 or neon in group 18?
neon is a noble gas that will not react with anything -- any other element except helium is more reactive than neon! With lithium, quite a reactive metal, it is certainly more reactive than neon.
Which element is more reactive than aluminum?
Many are thereSuch as Sodium, Potassium, Barium, Calcium, Magnesiumetc.
Which is more reactive barium magnesium or beryllium?
Ba; Barium
Which element would be most reactive be sr or ba?
Down a group the reactivity increases. So, barium (Ba) is more reactive than strontium (Sr).
Which element is more reactive - lithium Li or beryllium be?
Lithium is more reactive.
Which element is more reactive lithium of beryllium?
lithium
Which is more reactive barium or cesium?
if you mean pure barium as in barium metal then yes it is very reactive if you left a piece of it out in the open air over night it would turn to a pile of white barium oxide and other various compounds
Is lithium or Neon more reactive?
Lithium is more reactive than Neon.

What element is to be more reactive lithium or neon?
Lithium by far, it is an alkali metal. Alkali metals are known to explode when they are placed in water (hydrogen gas is released). Nitrogen has two electrons to fill, and alkali metals have one electron to give off. Think of it as 2>1. Just know that lithium is more reactive than nitrogen.
Which is more reactive fluorine or barium and why?
Fluorine would be the more reactive element because it needs to gain one electron. While Barium needs to gain two electrons. Thus it is easier to gain one than to lose two.
Which is more reactive barium magnesium or beryllium?
Ba; Barium
Which element would be most reactive be sr or ba?
Down a group the reactivity increases. So, barium (Ba) is more reactive than strontium (Sr).
Which is more reactive lithium or carbon?
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.
