Yes, there is a chemical element that fits this description: Silicon (Si). It has an atomic number of 14 and is classified as a semimetal. In the periodic table, group 4A is known as group 14, which includes both metals and semimetals. Semimetals are elements that exhibit properties of both metals and nonmetals, making them unique.
Silicon, in particular, is widely known for its role in electronics and computer chips, and it demonstrates the characteristic properties of a semimetal, including moderate electrical conductivity and a metallic luster. Therefore, the symbol of the semimetal in group 4A with an atomic number of 92 or less is Si.
