Answer 2

1.Example of metalloids is:-Borin,Silicon,Germanium,Arsenic, Antimony,Bismuth,Selenium, Tellurium,Polonium and Astatin.

2.Lustrous is the materials which show brightness on surfaces and reflect the light are called lustrous. For example:- Gold,Silver.

3.Sodium metal is soft enough to be cut with a knife .The Alkali metals are the elements in group 1(1A).They are lithium, sodium, potassium, rubidium, cesium and francium.

4.Malleability is the property due to which metals can be beaten into thin sheets.

5.Graphite is the non-metal that conduct heat and electricity .

6.Ductility is the property due to which metals can be drawn into wires. For example:-Copper and aluminum wires.
