Question

Which groups of the modern periodic table contain elements that are classified as metalloids?

A) Alkali metals and alkaline earth metals
B) Transition metals and inner transition metals
C) Metalloids and noble gases
D) Halogens and noble gases

Answer 1

Metalloids are located along the staircase line that divides metals and nonmetals in the modern periodic table, primarily in groups 13 through 16, including elements like boron and silicon.

Step-by-step explanation:

The groups of the modern periodic table that contain elements classified as metalloids are found along the staircase line that divides metals and nonmetals. This includes elements from groups 13 through 16. These elements, including boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), tellurium (Te), and perhaps polonium (Po), share properties of both metals and nonmetals. The options labeled A, B, and D in the provided question refer to groups that contain either metals or nonmetals but not metalloids.
