Refractory metal . The six elements that are widely known as the metalloids include silicon, germanium, antimony, arsenic, tellurium, and boron. Elements present to the left of the line of the periodic table are said as metals, though elements present to the far right of the periodic table are said as non-metals.Metalloids or semimetals are present just to the right of metals and possess properties of metals as well as non-metals.Hydrogen (H) is an exception, which is the first element of the periodic table and normal temperature and … is bismuth a metal ,nonmetal or metalloid Share with your friends.
