Question
As you move down the first group, reactivity _________.
- Increases
- Decreases
- Stays the same
- They are all inert
Hint:
As we move down the group 1 size increases.
The correct answer is: Increases
- As we move down the group 1 size increases.
- As the size increases the outer electrons are far away from the nucleus and can take part easily in reactions.
- As we move down the first group, reactivity increases.
