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 elements which show properties of both metals and non-metals.

In a periodic table, the elements on the left are metals and the elements on the right are non-metals. The elements placed between metals and non-metals are metalloids.

Out of the give options, polonium (Po), silicon (Si), and antimony (Sb) are metlloids.

Whereas selenium (Se), iodine (I), and phosphorous (P) are non-metals.

Tin (Sn) is a metal.

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

orbital diagram of carbon is as shown here in the image.
