How many elements are classified as metalloids in the periodic table?

1. Metalloids form a small diagonal band separating the metals from the nonmetals. 2. The text states: "A series of six elements called the metalloids separate the metals from the nonmetals in the periodic table. The metalloids are boron, silicon, germanium, arsenic, antimony, and tellurium." 3. Counting the six named elements confirms the total: boron, silicon, germanium, arsenic, antimony, tellurium. 4. So there are six recognized metalloids, not four, five, or eight. _Source: OpenStax Chemistry Ch 18 "Representative Metals, Metalloids, and Nonmetals", p.978 §18.3 Structure and General Properties of the Metalloids_
