Question

iv. Metals are conductors of electricity true or false​

Answer 1

Answer:

Metals are good conductors of electricity while non metals are bad conductivity as metal has lot of free electrons and therefore conducts while non metal does not have any free electron and does not conduct electricity.

Answer 2

Answer:

Yes. Metals are good conductors of electricity since the metallic bond gives rise to the” free electrons “ where outer orbit electrons of metal atoms are shared by many adjacent atoms and they are “loosely bound.

In ionic bond two atoms compliment. One gives an electron and the other atom receives the electron so that both becomes stable and bonded to produce a molecule. Like Sodium Chloride. Back.

In covalent bond two atoms share their outer orbit electrons . Like in H2 or Silicon Crystal.

Whereas in mettalic bond the outer electrons are shared by many atoms . It is like a servant who has multiple masters and he becomes free.
