Question

name two metalloids .why these elements are called metalloids? mention the position of metalloids in periodic table.

Answer 1

germanium and silicon are metalloids .They are called metalloid because they have the property of both metal and nonmetal. metalloid are placed in 13 14 15 16 group

Answer 2

Here is your answer....
_________________

Elements which have properties in between those of metals and nonmetals are called metalloids or semimetals .
_______________________

for example ...... Silicon , Germanium , arsenic , antimony and tellurium

_____________________

These elements show some properties of metal and other properties of non metals.
_________________

for example they look like metals but are brittle like non metals they are neither good conductors of electricity nor non conductors (insulators) like non metals. They are generally semi-conductors .

Metalloids lies between metals and non metals of the periodic table.
___________________

The metalloids are----
Boron (B), Silicon(Si) , Germanium (Ge) , arsenic (As), antimony (Sb) , tellurium (Te), polonium (Po), and Astatine (At).
