Using the Periodic Table, classify the following element as metal, nonmetal, or metalloid:

Antimony

Answer :

Antimony is classified as a metalloid due to its position in the periodic table and its properties bridging those of metals and nonmetals.

Based on the periodic table, Antimony (Sb) is classified as a metalloid. Metalloids exhibit properties characteristic of both metals and nonmetals. Antimony, in particular, shows allotropy and has oxidation states of +3, -3, and +5. It has properties similar to arsenic, such as high density, moderate thermal conductivity, and limited electrical conductivity. Antimony is often used in alloys and semiconductor materials.

Final Answer:

Antimony is classified as a metalloid.

Explanation:

Antimony (Sb) is classified as a metalloid on the Periodic Table. Metalloids are elements that exhibit properties of both metals and non-metals. They typically have characteristics intermediate between those of metals and non-metals.

In the case of antimony, it has some metallic properties such as being a good conductor of electricity, but it also exhibits non-metallic properties like brittleness. Its position in the Periodic Table, in Group 15 (sometimes referred to as the Nitrogen group), places it in the metalloid category.

Metalloids play important roles in various applications, especially in electronics and semiconductor industries, where their unique properties are harnessed for specific purposes. In the case of antimony, it is used in the production of certain types of semiconductors and as an alloying element in some metallurgical processes.
