Question

which group contains the most reactive nonmetals? group ia group viia group iia group viiia

Explanation:

To determine the group with the most reactive nonmetals, we analyze each group:

• Group IA: Contains alkali metals (e.g., Li, Na, K), which are highly reactive metals, not nonmetals.
• Group IIA: Contains alkaline earth metals (e.g., Be, Mg, Ca), also metals, not nonmetals.
• Group VIIA: Contains halogens (e.g., F, Cl, Br). Halogens are nonmetals and are highly reactive, especially fluorine, due to their strong tendency to gain an electron to achieve a stable electron configuration.
• Group VIIIA: Contains noble gases (e.g., He, Ne, Ar), which are nonmetals but are extremely unreactive (inert) due to their stable electron configurations.

So, Group VIIA has the most reactive nonmetals.

Answer:

B. Group VIIA
