Question

3 types of elements & describe them with 2 examples each .

Answer 1

There are three types of elements :

1) Metals : The metals are good at losing electrons, but they are poor at gaining electrons. The net effect is that the metals tend to lose electrons.They are good conductors of heat and electricity.

2) Non - Metals :  The nonmetals are poor at losing electrons, but they are good at gaining electrons. They gain electrons better than they lose them. So the nonmetals can be characterised by their ability to gain electrons. They are mainly insulators of heat and electricity. Though their are some exceptions also.

3) Metalloids : An element (e.g. arsenic, antimony, or tin) whose properties are intermediate between those of metals and solid non-metals or semiconductors are called metalloids.
