Final answer:
Metalloids are somewhat reactive, can be used to make semiconductors, and have properties of both metals and nonmetals.
Step-by-step explanation:
The three statements that apply to metalloids are:
- They are somewhat reactive: Metalloids exhibit some reactivity, but not as much as metals.
- They can be used to make semiconductors: Metalloids, like silicon and germanium, have properties that make them useful for the production of semiconductor materials.
- They have some properties of metals and some of nonmetals: Metalloids exhibit characteristics of both metals and nonmetals, making them intermediate in nature.
