write the difference between metal and non metal
Answers
Answer:
Heya Mate:
- Metals are Good conductor of heat and electricity.
Non Metals are bad conductor of Heat and electricity
- Metals are Shiny.
- Non metals are dull
physically:
metals are solid at room temperature. Mercury is the only metal which is found in liquid state. metals are malleable and ductile. metals are lustrous. metals are good conductor of heat and electricity. metals have high tensile strength. metals are sonorous. metals are generally hard. metals have high melting and boiling points.
non metals are generally soild or gaseous. non metals are brittle. non metals are non lustrous. non metals are poor conductor of heat and electricity. non metals are quite soft. non metals are non sonorous. non metals have low tensile strength. non metals have low boiling and melting points.
chemically:
most of the metals react with oxygen and form basic oxides. metals react with water to form metals hydroxide and metal oxides and hydrogen gas. metals react with acids to form respective salts and hydrogen gas. reactive metals react with bases to form their respective salts and hydrogen gas. metals show displacement reaction.
non metals react with oxygen to form acidic or neutral oxides. non metals do not react with water under normal conditions. non metals do not react with acids. reaction of non metals with bases in complicated. most of the non metals do not show displacement reaction but certain more reactive non metals displace less reactive non metals from their salt solutions.
