My science teacher says that Astatine is a nonmetal.

Astatine is a nonmetal and halogen.

Astatine is a radioactive halide (non-metal), not enough of it exists to determine its physical characteristics.

it's a non-metal, is what wikepedia says

No, the guy before me was wrong, Astatine is a Metalloid and it is used in the Radiotherapy of cancer.

Astatine is a heavy halogen; no similarities with strontium (alkaline earth metal).

No. Astatine is a halogen. The alkaline earth metals are in the column second from the left of the periodic table.

Yes. A solid nonmetal of the halogen family.

According to Lange, Semi-metals are: boron, silicon, germanium, arsenic, antimony, tellurium, polonium and astatine. Although, polonium and astatine, according to some authors, are not semi-metals. Gallium is a metal (4. period, 13th (IIIa) group).

Astatine is not a good conductor of electricity. This is because it is a non-metal. All non-metals do not conduct electricity, and all metals do. The one exception is carbon, which is a non-metal, but conducts electricity well.

In 1940, astatine was produced in a lab at the University of California by the three scientists named Carson, Mackenzie, and Segre. This element is classified as a semi-metal and has the atomic number of 85.

Astatine, with the symbol At and the atomic number 85, is usually classified at a metalloid, but this is in dispute. It is sometimes classified as a halogen, and possibly a metal. It is still being studied.

It is usually considered a metalloid, but also sometimes considered a halogen or just a plain ol' metal.
