Which two groups of elements in the periodic table are the most reactive?(1 point)Responseshalogens and noble gaseshalogens and noble gasesalkaline earth metals and halogensalkaline earth metals and halogensalkali metals and halogensalkali metals and halogensnoble gases and alkali metals

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 eagerness to lose one electron to form positive ions, while halogens (Group 17) are very reactive nonmetals that readily gain an electron to achieve a stable electron configuration. So the correct response is **alkali metals and halogens**.
