Question

Metals conduct electricity because
(a) they have several valence electrons
(b) their valence electrons are not involved in
making metallic bond
(c) they have lattice of +ve ions
(d) they have a lattice of +ve surrounded by
mobile electrons​

Answer 1

Answer:

Metals conduct electricity because the electrons inside the metal are relatively free to move. So when electricity is pass through metals, electrons carry electricity and spread it all over the metal. The mobility of electrons is the reason why metals conduct electricity.

Answer 2

Answer:

I think option (d) is the right answer.
