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.
