Question

Why are metals good conductors of electricity? h​

Answer 1

Answer:

Electric current is the flow of electrons in a wire. In metals, the outer electrons of the atoms belong to a 'cloud' of delocalised electrons. They are no longer firmly held by a specific atom, but instead they can move freely through the lattice of positive metal ions. ... Metals are good conductors of heat.

Answer 2

$\huge \underline \mathbb \orange {ANSWER :-}$

Metals are good conductors of electricity because they contain free electrons. These free electrons move easily through the metal and conduct electric current.
