Nonmetal
Metalloid
The seven metalloids are boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), tellurium (Te), and astatine (At). On a standard periodic table, they occupy a diagonal area in the p-block extending from boron at the upper left to astatine at lower right, along the dividing line between metals and nonmetals shown on some periodic tables.

5	Sb 2.05	Te 2.1	I 2.66	Xe (2.4)

6	Metalloids	At 2.2	Rn (2.06)

Electronegativity (EN) gives some indication of nonmetallic character. The metalloids have uniformly moderate values (1.8–2.2).
