Verified Answer
The pair of semimetals in the following is:a)Al, Sib)Ge, Sic)Sb, Ted)C...
A semimetal is a material with a very small overlap between the bottom of the conduction band and the top of the valence band. According to electronic band theory, solids can be classified as insulators, semiconductors, semimetals, or metals. except Aluminum - can be considered a semi-metal/metalloid: To be thorough, those elements are: Boron (B), Silicon (Si), Germanium (Ge), Arsenic (As), Antimony (Sb), Tellurium (Te), Polonium (Po), Iodine (I), and Astatine (At). There are two elements that can be considered semi-metals that are in the 7th period, but because they’re not found in nature, I skipped them.

The pair of semimetals in the following is:a)Al, Sib)Ge, Sic)Sb, Ted)C...
The pair of semimetals in the given options is Sb (antimony) and Te (tellurium), which is option C.
Explanation:
Semimetals, also known as metalloids or semiconducting metals, are elements that possess properties of both metals and nonmetals. They lie on the boundary between metals and nonmetals in the periodic table.
Let's examine each option to determine the pair of semimetals:
a) Al (aluminum) and Si (silicon):
- Aluminum is a metal and not a semimetal.
- Silicon is a semiconductor, which is a type of semimetal, but not a true semimetal. It is commonly classified as a metalloid due to its intermediate properties.
b) Ge (germanium) and SiC (silicon carbide):
- Germanium is a semimetal. It possesses both metallic and nonmetallic properties.
- Silicon carbide (SiC) is a compound and not an element. It is a ceramic and does not fall under the category of semimetals.
c) Sb (antimony) and Te (tellurium):
- Antimony is a semimetal. It has a metallic appearance but exhibits nonmetallic properties.
- Tellurium is also a semimetal. It is brittle and exhibits both metallic and nonmetallic properties.
d) Ca (calcium) and B (boron):
- Calcium is a metal and not a semimetal.
- Boron is a nonmetal and not a semimetal.
Therefore, the correct pair of semimetals in the given options is Sb (antimony) and Te (tellurium), which is option C.
