​

Answer 1

$\huge{\underline{\tt{\green{Metals-}}}}$ The elements which have metallic bonds and have positive ions.

Let's know some properties of metals -

• They are lustrous.

• The are the good conductor of electricity and heat.

• Generally they are solid (except mercury).

• The are ductile (can be drawn into wires).

• The are malleable (can be convert into sheets).

• The are sonorous make a ringing sound.

• For example - Gold (Au), silver (Ag), copper (Cu), iron (Fe), Sodium (Na), Potassium (K) etc.

$\huge{\underline{\tt{\green{Non-metals-}}}}$ Non-metals have lack properties of non-metals.

Let's know some properties of Nonmetals -

• The are found in different colours.

• They are poor conductor of electricity and heat.

• The are not lustrous ( except graphite).

• They are not sonorous.

• They are non ductile and non malleable.

• For example - Hydrogen, Oxygen, Iodine, Carbon etc.
