differentiate between metals and non metals on the basis of physical properties
Answers
Difference between Metals and Non-Metals on the basis of Physical Properties :
Metals : All metals(except Mercury,which is liquid) are solid at room temperature. Ex - Iron,Copper,Gold e.t.c
Non-Metals :They may exist in solid, liquid or gaseous state. Ex - Carbon,Iodine
Metals : They generally have high melting as well as high boiling points. Ex - Melting Point of Iron is 1536℃ and its boiling point is 3000℃. Some metals have exceptionally low melting point. Ex - Caesium melts at only 38.7℃
Non-Metals : They have generally low melting points as well as low boiling point. Ex - Melting point of Sulphur is 119℃. Exception in Non-Metal is Diamond It has melting point of 3723℃
Metals : They generally have high density. The exception case is Sodium and Potassium.
Non-Metals : They generally have a low density.
Metals: Most Metals are very hard. They can withstand quite high pressure without getting distorted.Exception - Sodium and Potassium
Non-Metals : Non-Metals are generally not hard; they are brittle and easily break into pieces when hammered. Exception - Diamond
Metals : They have shining surface known as Metallic Lustre.
Non-Metals: They generally have dull appearance. Exception - Iodine
Metals : They are Malleable
Non-Metals: They are non-Malleable.
Metals : Metals are Ductile
Non-Metals : Non-Metals are non-ductile.
Few other Physical Properties are Tensile Strength, Conductivity and Sonorisity
Differentiation between the properties of metals and non -metals.
♡
✯Metals are malleable and can be converted into thin sheets.
✯Examples - Iron, Aluminium.
✯Non metals are not malleable.
✯Examples - Sulphur, carbon.
♡
✯Metals are ductile and can be changed into thin sheets.
✯For ex - Gold,silver.
✯Non-metals are not ductile.
✯For ex - Sulphur, carbon.
♡
✯Metals are lustrous ,they have shiny appearance.
✯example- Gold,silver.
✯Non-metals are non -lustrous ,they have a dull appearance,except Diamond and Iodine.
♡
✯Metals are good conductor of heat and electricity.
✯Silver metal has highest thermal and electrical conductivity.
✯Non-metals are bad conductor of heat and electricity,except graphite which is a good conductor of electricity.
♡
✯Metals are generally hard,except sodium and potassium.
✯They both can be cut with a knife.
✯Non-metals are generally soft,except Diamond.
✯Diamond is hardest substance ever known.
♡
✯Metals generally have high melting and boiling points ,like Copper has melting point of 1083°C and iron has 1535°C ,except Caesium and gallium [low melting and boiling points.
✯Non metals have low melting point except Diamond [3723°C].
♡
✯Metals are generally found in solid state ,except Mercury which is liquid in room temperature.
✯Non metals may be solid , liquid or gas at room temperature.
♡
✯Metals have high density,except sodium and potassium.
✯Non metals have low densities
♡
✯Metals are sonorous,they produce ringing sound.
✯Non-metals are non sonorous.
