Which element is a metalloid? check all that apply. selenium (se) polonium (po) silicon (si) iodine (i) tin (sn) antimony (sb) phosphorus (p)

Explanation:

Metalloids are the substances which show properties of both metals and non-metals.

Metalloids are moderately able to conduct heat and electricity. Generally metalloids are solid at room temperature. They are also able to react with other molecules.

For example, in a periodic table metalloids are boron, silicon, germanium, arsenic, antimony, tellurium and polonium.

Thus, we can conclude that out of the given options selenium (Se), polonium (Po), silicon (Si), and antimony (Sb) are the metalloids.
