Question

Which two groups of elements in the periodic table are the most reactive?(1 point) Responses noble gases and alkali metals noble gases and alkali metals alkaline earth metals and halogens alkaline earth metals and halogens alkali metals and halogens alkali metals and halogens halogens and noble gases

Answer 1

The two groups of elements in the periodic table that are the most reactive are the **alkali metals and halogens**.

- Alkali metals (Group 1) are highly reactive, especially with water and halogens.
- Halogens (Group 17) are also highly reactive, often forming salts with alkali metals.

So, the correct response would be **alkali metals and halogens**.
