Question

bromine, chlorine, and fluorine are examples of ______. a halogens b metalloids c noble gases d alkali metals

Explanation:

Halogens are elements in Group 17 of the periodic table. Bromine (Br), chlorine (Cl), and fluorine (F) are all in Group 17, so they are halogens. Metalloids have properties between metals and non - metals (e.g., silicon), noble gases are in Group 18 (e.g., helium), and alkali metals are in Group 1 (e.g., sodium). So the correct option is A.

Answer:

A. halogens
