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.
Well, umm... as you go down a group the reactivity of metals is larger. This is because the atomic radius gets larger when you go down the family. Therefore electrons will be added succesively. Outer energy levels which are located further from the nucleus. Valence electrons are also shielded from the affects on the nuclear charge by inner electrons and therfore they orbit further away. Sooo the ionization eneregy becomes larger and therefore less energy is required to overcome the weaker nuclear attraction.

i don't think that entirely makes sense? because i have just used it for my science and it doesn't sound quite right. M x
Here is my answer to this:
Lithium, sodium and potassium
These elements are very reactive - they will even react (causing an explosion) with water.
The reason why they are so reactive is that the elements are desperate to get rid of that single, untidy electron in the outer shell, and the bigger the atom is - the more it wants to get rid of the electron.
This means that the atoms get bigger as you go down the group and they also become more reactive(and more dangerous).
So, sodium is more reactive than lithium and potassium is more reactive than both of them.
I hope this answer helps, i dnt rlly kno alot bout this subject

Sodium's valence electron is in the third energy level, while lithium's valence electron is in the second energy level. Sodium's valence electron is further from the positively charged nucleus than lithium's valence electron, so it is held less tightly than lithium's valence electron. Therefore, it is easier for sodium to lose its valence electron so it reacts more vigorously with water than does lithium.
The ionization energy of lithium is a bit greater than the ionization energy of sodium. Sodium is more reactive.
The ionization energy of lithium is greater than the ionization energy of sodium, and soium is consequently more reactive.
sodium,because group 1 is the strongest group metals and as you go down the group reactivity increases as atoms get larger
The ionization energy of lithium is greater than the ionization energy of potassium, and potassium is consequently more reactive.
Lithium is not more reactive than sodium and potassium.
Na is more Electropositive than Li.
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.
Sodium is more reactive than sulfur.
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.
Aluminium is much less reactive than Lithium.
Yes.

Lithium is more reactive than Neon.
sodium is more reactive than magnesium!
Sodium is in the middle of those 2
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.
sodium is more reactive than magnesium!

No, titanium is less reactive than sodium.
Yes.
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.
