Metalloids are elements that have some properties of both metals and nonmetals. The term isn’t precise, and scientists vary on which elements they consider to be metalloids, but generally boron, silicon, germanium, arsenic, antimony, and tellurium fall under this categorization. Sometimes, bismuth, polonium, and astatine are considered metalloids, although that is less common.
The correct answer to this quiz is Metalloids.
