Chemical Properties of Metals
The density of metals is usually high.
Metals are malleable and ductile.
Metals form an alloy with other metals or non – metals.
Some metals react with air and corrode. ...
Metals are good conductors of heat and electricity. ...
Generally, metals are in a solid state at room temperature.
Metals:-
⇒ Physical state :- Metals are solid at room temperature except mercury and gallium
⇒ Melting & Boiling points :- Metals have high melting and boiling point except gallium and cesium
⇒ Density :- Generally have high density
⇒ Malleability & Ductility:- Metals are malleable and ductile
⇒ Electrical & Thermal conductor :- Good conductor of heat and electricity
⇒ Luster :- pososs shining luster
⇒ Sound :- Metals give sonorous sound
⇒ Hardness :- Generally hard except postassium ( K ) and sodium ( Na )
Non metals :-
⇒ Physical state :- Non metals generally exist as solid and gases except Bromine.
⇒ Melting & boiling point :- they have low melting and boiling point except diamond and graphite
⇒ Density:- Generally low density
⇒ Malleability and Ductility:- Neither Malleable nor Ductile
⇒ Electrical and thermal conductor :- poor conductor of heat and electricity except graphite.
⇒ Luster :- Do not have luster except Iodine
⇒ Sound :- Does not give sound
⇒ Hardness :- Gernerally Soft except Diamond.
