Question
Metals are good conductors of electricity. Explain.
✓
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.
