That would be boron.
No, krypton is not a semimetal. It is a noble gas found in group 18 of the periodic table and does not exhibit the properties of a semimetal.
No, xenon is a noble gas in Group 18 of the periodic table. It is nonmetallic and does not exhibit properties of a semimetal.

Boron is the only mettaloid in Group 13
No, K, or potassium, is not considered a semimetal. It is considered part of the metal group in the periodic table.
Boron is not classified as a semimetal. It is a metalloid, meaning it has properties that are intermediate between metals and nonmetals. Nitrogen, on the other hand, is a nonmetal.

No, gold is not a semimetal. It is a metal due to its properties such as high electrical conductivity, malleability, and ductility. Semimetals have properties that are intermediate between metals and nonmetals.
Tellurium is a semimetal. Some people consider it a metalloid, but it's not that. The only metalloids I know of are Arsenic and Antimony.
sodium is a metal; silicon is a semimetal (metalloid); helium and sulfur are non metals
Plastic is a type of material known as a polymer, which is a nonmetal in terms of its composition. It is not classified as a metal or a metalloid (semimetal).
