A. Groups 1–2
B. Groups 3–12
C. Groups 13–16
D. Groups 17–18

Respuesta :

C. Groups 13-16 contain metalloids.

If you look on a periodic table, these usually have a different color.

Answer:

Groups 13-16.

Explanation:

There are 18 groups in the periodic table.

The first and second group contains only metal (alkali and alkaline earth metals)

The third to twelfth group (3-12) also contains only metals (the transition metals and inner transition metals).

Now the groups from 13 to 18 contains metals, non metals and metalloids

group 17-18 are strictly non metals

Thus the metalloids find their place in groups 13-16.
