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)

In the periodic table, metalloids occur along the diagonal line from boron to polonium. Elements to the upper right of this line are nonmetals; elements to the lower left are metals.

metals are discovered often on the amazing facet of the periodic table (the 1st 2 communities and transition metals)...they often take part in steel bonding by utilising sharing their valence electrons by using delocalization. this belongings makes them sturdy conductors of electricity and warmth. they often lose electrons and style cations. metals are vivid and have luster, they're ductile/malleable. they style uncomplicated oxides. non-metals are those factors on the left facet of the periodic table. they benefit electrons to alter into anions/fill their electron shells. it somewhat is through fact a lot of them have intense electronegativities non-metals are insulative meaning they're adverse conductors of warmth and electricity. they contain the noble gases (an prolonged way appropriate column of the periodic table) and halogens (maximum uncomplicated halides are fluorine, iodine, bromine and chlorine). nonmetals exist specifically in the gasoline area, aside from bromine that's liquid at room temperature. nonmetals style acidic oxides. they're brittle. they have decrease melting & boiling element temps than metals, and frequently decrease densities. metalloids are style of in between metals and nonmetals, so they have homes of the two. the main uncomplicated ones are silicon, arsenic, germanium, boron. metalloids frequently function semiconductors. they're solids at room temperature and that they are brittle
