What makes a material electrically conductive on the atomic level?

The electrically charges particles make the material electrically conductive on the atomic level. In metals, the valence electrons are responsible for conduction. More the valence electrons, more the movement of charge, more conductivity.

What’s the question

4- c, because all matter stays the same no matter what. it is still there. 5- b, because matter is known as mass. 6-c because, flammability is a chemical property. malleability is changing the shape of an object.
