Its due to their location on the table. Lithium and sodium are in the same family, (column) so they have similar properties. Sodium is not in the same family as magnesium, so their properties differ slightly
They are alike because lithium is more closely related to magnesium than to the other alkali metals. lithium has an atomic radius of 152 pm and ionic radius of 76 pm. magnesium has an atomic radius of 160 pm and an ionic radius of 72 pm. these similar physical properties lead to similar chemical properties, which is why lithium and magnesium have a diagonal relationship.
The property of metal is to lose electrons while bonding and Na losses electrons readily 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 has a larger atomic radius and is more metallic.
Because the atomic weight of sodium is greater than the atomic weight of lithium; sodium is under lithium in the column of alkali metals.
The element in Period 3 that has the greatest metallic character is magnesium. In periods, the metallic character decreases when atomic number increases.
Sodium is more reactive than lithium because sodium has an extra electron in its outer shell, making it easier for sodium to lose that electron and form a stable ion. This extra electron also makes sodium more likely to react with other substances to achieve a stable electron configuration.
Yes, lithium chloride is more soluble.
aluminium is more metallic than sodium because in metals the element which has the most electron in the outer most shell is more metallic . that means that Al is more metallic. sodium is reactive but aluminium is metallic. that'swhy its used for making aluminium wires ...
sodium is a softer metal than lithium.
Na is chemically more like Li than Mg, only physically (measurements, mass) it looks more like Mg
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 in the middle of those 2
Sodium is more reactive than lithium because sodium has an extra electron in its outer shell, making it easier for sodium to lose that electron and form a stable ion. This extra electron also makes sodium more likely to react with other substances to achieve a stable electron configuration.
Lithium is more reactive than Neon.
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.
