Question
How would you describe reactivity on the Periodic Table?
- Elements in the same period tend to react.
- Elements in the same group tend to react.
- Elements on opposite sides of the table tend to react.
- All elements are inert.
Hint:
Cations and anions tend to react.
The correct answer is: Elements on opposite sides of the table tend to react.
- Reactivity decrease as you go left to right of the periodic table, reactivity increases as you go down the group.
- Left side elements in the periodic table form cations and right side elements form anions.
- Elements on opposite sides of the table tend to react.
