Question
Is the reaction of rubidium with water more or less vigorous than that of sodium? How does the rate of reaction of magnesium compare?
Step 1
The reactivity of metals increases as we move down the group in the periodic table. This is because the atomic size increases down the group which makes the outermost electron more easily removable and hence increases reactivity. Show more…

Go Figure 7.21 Part A Would you expect rubidium metal to be more or less reactive with water than sodium metal? The alkali metals react vigorously with water. Rubidium metal is more reactive with water than sodium metal. Rubidium metal is less reactive with water than sodium metal.
which is more reactive, Rubidium or Hydrogen?
Sodium reacts with water more vigorously than lithium because: (a) it has higher atomic mass (b) it is more electropositive (c) it is more electronegative (d) it is a metal
