Question

Why are metals good conductors of heat and electricity?

Answer 1

Metals are an excellent conductor of electricity and heat because the atoms in the metals form a matrix through which outer electrons can move freely. Instead of orbiting their respective atoms, they form a sea of electrons that surround the positive nuclei of the interacting metal ions.

Step-by-step explanation:

Answer 2

Almost all existing metallic elements are conductor of electricity, although the conductance varies according to the element. The chemical elements that are considered as very good conductors are as follows:

Copper

Silver

Aluminum

Gold

Nickel

Chromium

Iron

Magnesium

Mercury

Titanium

Molybdenum
