Question

Explain the metals are good conductor of electricity with the help of an activity

Answer 1

Answer:

Metals contain free electrons. When potential difference is applied at the ends of a metal rod, the electrons respond to it and start moving towards the positive terminal,of battery. This flow electrons result in the conduction of electricity through the metal.

Answer 2

Answer:

(1) Metals are good conductors of electricity since the outermost electrons of atoms in metallic crystal occupy conduction bands.

(2) The number of electrons in conduction bands is very large.

3) The conduction bands in metals can be labelled as s band, overlapping s and p bands etc. according to overlapping of orbitals.

(4) This results in delocalisation of outermost electrons forming metal ions. Hence, this is analogous to metal cations immersed in the sea of electrons.
