Question

Write the chemical properties of metals and non-metals.

Answer 1

1. Reaction with oxygen
. Metals react with oxygen to form metal oxides metal oxides are basic in nature.
Metal + oxygen= metallic oxide

2. Reaction with water
. When a metal reacts with water then I'm metal hydroxide and hydrogen gas are formed. Metal + water - - -metal Hydroxide + oxygen
3. Reaction with Acids
. Most of the metals react with dilute acid to form Salts and hydrogen gas.
Metal + acid --- salt + hydrogen
4. Reaction with bases
. Some metals react with base to form Salts and hydrogen gas.
. Metal + base ---- salt + hydrogen

Answer 2

metals:
. has the higher resistivity
. higher temperature resistance
. stronger then the non metals
. the ductility is more
.wears the heavy loads
. they are the good conductors of electricity
. they are conductors

non metals:
. they are no corrosive
. the deformation is easily taken place.
. can't bear the heavy loads
. has the lower temperature resistance
.they won't allow the current to pass through them
. they are insulators
