Rubidium is more reactive than sodium because rubidium has a larger atomic radius and fewer electron shells, making it easier for rubidium to lose an electron and form a positive ion. This tendency to lose an electron increases its reactivity compared to sodium.
Rubidium is more reactive than krypton. Rubidium is an alkali metal and reacts vigorously with water, while krypton is a noble gas and is inert under normal conditions.
Rubidium has a larger atomic radius than sodium because rubidium has more electrons and energy levels, leading to increased electron-electron repulsion and a larger atomic size. Additionally, the outermost electron in rubidium is in a higher energy level compared to sodium, contributing to a larger atomic radius.
Sodium has a melting point of 97.72 oC and rubidium has a melting point of 39.48 oC.
Sodium is more reactive than sulfur because sodium belongs to Group 1 of the periodic table, which means it has one valence electron that it readily gives up to form compounds. Sulfur, on the other hand, belongs to Group 16 and tends to gain electrons to form compounds, making it less reactive than sodium.
Sodium is more reactive than iron because sodium has a higher tendency to lose electrons and form ions compared to iron. Sodium reacts vigorously with water and air, while iron reacts more slowly under normal conditions.
The atomic radius of potassium is greater than that of sodium. Therefore, the single valence electron that exists for all alkali metals is located farther from the nucleus for potassium than sodium. This results in less energy required to remove that valence electron from potassium than from sodium, leading to increased reactivity. Note that this trend continues as you move down Group I on the Periodic Table, meaning that Rubidium is more reactive than Potassium and Cesium is more reactive than Rubidium.

Rubidium is more reactive than krypton. Rubidium is an alkali metal and reacts vigorously with water, while krypton is a noble gas and is inert under normal conditions.
No, titanium is less reactive than sodium.

Sodium
Sodium is more reactive than lithium and magnesium but less reactive than potassium.
Sodium is more reactive than either magnesium or iron.
Rubidium has a larger atomic radius than sodium because rubidium has more electrons and energy levels, leading to increased electron-electron repulsion and a larger atomic size. Additionally, the outermost electron in rubidium is in a higher energy level compared to sodium, contributing to a larger atomic radius.
Sodium has a melting point of 97.72 oC and rubidium has a melting point of 39.48 oC.
sodium because it's the first group and first group are the most
