Both cesium and lithium react by giving up the single electron int their outer shells. Cesium has a larger atomic radius than lithium does and more electron shells between the nucleus and the outer shell. As a result, cesium's valence electron is less attracted to the nucleus than Lithium's is and is therefore more easily removed.

Cs has more electrons (44 more electron) than Na. The electrons in the outer electronshell are further away from the positive nucleus because there are many more electron shells.
Because the valence electrons are further from the nucleus they are not held as tightly by the atom, this means that it takes less energy to remove the electron in the outer electron shell from Cs.
So it is more reactive.

What metal is more reactive than cesium?
Plutonium is more reactive than Cesium.
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.
Which one is the most reactive metal potassium lithium or sodium?
Cesium. Cesium is the bad boy of the alkali metals, a period that's just jam-packed with seriously nasty elements. Cesium is reactive enough that if you were to put some water into dry ice, and wait till the ice got that cold itself before putting some cesium on it, the cesium would still react with it! Here's a remembrance: the higher an alkali metal's atomic number, the more reactive it is.
Which is the less reactive - aluminum or lithium?
Aluminium is much less reactive than Lithium.
Is lithium more reactive than aluminum?
Yes.

Is lithium or Neon more reactive?
Lithium is more reactive than Neon.
Is francium more or less reactive than cesium?
Francium is considered to be more reactive than caesium.
Is magnesium more reactive than lithium?
Lithium is more reactive to water than magnesium because while Lithium will explode and generally destroy the container it is in, magnesium will cause the water to violently bubble.
Would you expect cesium element 55 to be more or less reactive than potassium?
more reactive
Which is the less reactive - aluminum or lithium?
Aluminium is much less reactive than Lithium.
Which is reactive cesium or francium?
In reaction with water and oxygen Fr is more reactive than Cs
Why is cesium more reactive than sodium?
because it is less stable
Is the lithium atom bigger than the Cesium atom?
Not at all; the cesium atom is far bigger than the lithium atom.
Is lithium more reactive than aluminum?
Yes.
