Question

The elements in Groups 1 and 2 get more reactive as you go down the group.
This means that _______________ is more reactive than lithium and ____________________ is more reactive than beryllium.

Answer 1

Answer:

Sodium and Magnesium

Explanation:

The elements in Groups 1 and 2 get more reactive as you go down the group.

This means that Sodium is more reactive than lithium and Magnesium is more reactive than beryllium.

On the periodic table, as you go down the group, the reactivity of an element increases. Especially with metals in group 1 and 2. Now Lithium is a metal of group 1, followed by Sodium, while Beryllium is a metal in group 2, followed by magnesium. That's how I picked the answers
