Answer :
Final answer:
A metalloid is an element with properties intermediate between those of metals and nonmetals, usually found along the 'stair-step' line on the periodic table.
Explanation:
A metalloid is not the same as a metal, nor is it located on the left side of the periodic table. Instead, a metalloid is an element having properties intermediate between metals and nonmetals. These properties include a combination of metallic and nonmetallic characteristics. For example, metalloids may exhibit semiconductive behavior, which is invaluable in electronics and technology. On the periodic table, metalloids are typically located along the 'stair-step' line that distinguishes metals from nonmetals. Therefore, the correct answer to the student's question is option 3) having properties intermediate between metals and nonmetals.

Final answer:
A metalloid is: having properties intermediate between metals and nonmetals.
Therefore, the correct answer is option 3
Explanation:
A metalloid is an element that exhibits properties intermediate between metals and nonmetals. Therefore, the correct answer is option 3) having properties intermediate between metals and nonmetals.
Metalloids are located on the zigzag line of the periodic table, which separates metals from nonmetals. They include elements such as boron, silicon, germanium, arsenic, antimony, and tellurium.
Metalloids possess some characteristics of metals, such as the ability to conduct electricity, but they also exhibit nonmetallic properties, like brittleness. Their properties make them useful in various applications, such as semiconductors in electronic devices.
So, to summarize, a metalloid is an element that displays properties that are intermediate between metals and nonmetals.
Therefore, the correct answer is option 3
