Answer 1

The most reactive groups of elements in the periodic table are the **alkali metals and halogens**. Alkali metals (group 1) are highly reactive due to their tendency to lose one electron, while halogens (group 17) are reactive because they tend to gain one electron to achieve a full outer shell.
