what are metalloids?

Answer 1

Together with the metals and nonmetals, the metalloids (in Greek metallon = metal and eidos = sort) form one of the three categories of chemical elements as classified by ionization and bonding properties. They have chemical properties intermediate between those of metals and nonmetals. For example, their oxides are often amphoteric. Their electronic properties vary from those of semiconductors (B,Si,Ge) to semimetals (eg. Sb). The concepts metalloid, semiconductor and semimetal should not be confused. Metalloid refers to the chemical properties of certain elements in relation to the periodic table. Semiconductor and semimetal refer to the physical properties of materials (including alloys, compounds) and there is only partial overlap between the two.

The known metalloids (and their atomic symbols) are:

Boron (B)
Silicon (Si)
Germanium (Ge)
Arsenic (As)
Antimony (Sb)
Tellurium (Te)
Polonium (Po)
Astatine (At)

Answer 2

What Are Metalloids

Answer 3

metalloids are the elements that are in between metels and nonmetals. On a periodic table, they are located around the "steps" that start at boron and go down and to the right. Metalloids have properties of both metals and nonmetals. For example, Silicon conducts electricity like metal, but it doesnt react much with acids which is like most nonmetals

Answer 4

The metalloids can be defined as those elements which exhibit characteristics of both metals and nonmetals. They are all solids, but not lustrous, and conduct heat and electricity moderately well.

Answer 5

Metalloids fall on the periodic table between the metals and the nonmetals. They are called metalloids because sometimes they act like metals and sometimes act like nonmetals. When with a metal they act like a nonmetal, when with a nonmetal they act like a metal.
