State
Group 2 metals are less reactive than group 1 metals in the same period because higher nuclear charge raises ionization energy and shrinks radius.
Show
Magnesium reacts with water far more slowly than sodium, its group 1 neighbor.
Watch for
Less reactive does not mean unreactive — heavier alkaline earth metals still react vigorously enough to need careful handling.
