Question

chemical properties onthe basis on which metals and non metals are classified​

Answer 1

Silicon for example appears lustrous, but is not malleable nor ductile (it is brittle - a characteristic of some nonmetals). It is a much poorer conductor of heat and electricity than the metals. The physical properties of metalloids tend to be metallic, but their chemical properties tend to be non-metallic.

Answer 2

Chemical Properties of Non-Metals

1)Non-metals generally contain 4-8 electrons in the outer shell

2) Non-metals can readily lose or gain valence electrons When they come in contact with oxygen, non-metals form acidic oxides

3)Non-metals are highly electronegative elements

These elements are great oxidizing agents

4)Non-metals do not react with water

Chemical Properties of Metals

1)Metals are very easily corrodible

2)Metals are known to lose electrons

3)Most metals when they come in contact with the oxygen they form metal oxides

3)They have lower electronegativities, they are generally electropositive elements

4)Metals can act as very good reducing agents
