The statement of an element classified as a semimetal (metalloid) is "period 4, group 15."
What is metalloid?
A metalloid is an element with properties that fall between between those of metals and those of nonmetals. In addition to metals, nonmetals, or both, groups 13–16 of the periodic table contain one or more metalloids. Boron, silicon, germanium, arsenic, antimony, tellurium, and polonium are common semimetals or metalloids. Tennessine and oganesson are also considered metalloids by certain scientists. Group 15 of the periodic table is also known as the nitrogen group, and the metalloids in this group include arsenic (As) and antimony (Sb). Arsenic is found in the fourth period/row of the periodic table.
Hence the correct option is Period 4, Group 15.
