Are tellurium and polonium metalloids?
The elements boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), tellurium (Te), polonium (Po) and astatine (At) are considered metalloids.
Is bromine a metalloid?
Bromine is the third halogen, being a nonmetal in group 17 of the periodic table. Its properties are thus similar to those of fluorine, chlorine, and iodine, and tend to be intermediate between those of the two neighbouring halogens, chlorine, and iodine.

Are there 7 or 8 metalloids?
The eight elements classified as metalloids are boron, silicon, germanium, arsenic, antimony, tellurium, astatine, and polonium. Metalloids occur along the diagonal stair-step between metals and non-metals.
What are the six metalloids?
The six commonly recognised metalloids are boron, silicon, germanium, arsenic, antimony, and tellurium. Five elements are less frequently so classified: carbon, aluminium, selenium, polonium, and astatine.
Is tellurium found in the human body?
In humans, tellurium is partly metabolized into dimethyl telluride, (CH3)2Te, a gas with a garlic-like odor exhaled in the breath of victims of tellurium exposure or poisoning.
