differntiate between chemical properties of metal and non metal
Answers
Answer:
Metals Non-Metals
1 Metals are malleable. Non-metals are non-malleable or brittle.
2 Metals are ductile. Non-metals are non-ductile
3 Metals are good conductors of heat and electricity. Non-metals are bad conductors of heat and electricity.
4 Metals are Lustrous and can be polished. Non-metals are non-lustrous and cannot be polished.
5 Metals are solid at room temperature. Non-metals may be solid, liquid or Gases at room temperature.
6 The melting and boiling points of metals are generally high. Non-metals have low melting and boiling points as compared to metals.
7 All metals are strong. Non-metals are not strong.
8 Generally, metals are hard. Most of Non-metals are soft.
9 Metals are heavy. Non-metals are light substances.
10 Metals are sonorous. Non-metals are non-sonorous.
1 1All metals react with oxygen to form metal oxides All non-metals react with oxygen to form acidic or neutral oxides.
12 Metals react with water to produce metal oxide (or metal hydroxide) and hydrogen gas. Non-metals do not react with water.
13 Metals react with a dilute acid to form a metal salt and hydrogen gas. Non-metals do not react with dilute acids .
14 All metals react with chlorine to form ionic metal chlorides. Non-metals react with chlorine to form covalent chlorides.
15 Only a few metals like Na, K, Ca and Mg react with hydrogen to form metal hydrides. Non-metals react with hydrogen to form covalent Hydrides.
Answer:
Metals
- they have lustre
- they have silvery-grey or golden- yellow colour
- they conduct heat and electricity
- they are ductile
- they are malleable
- they are sonorous
Non-metals
- they display a variety of colours
- they are poor conductors of heat and electricity
- they are not lustrous, sonorous or malleable
