Question

Metals are great conductors because

the electrons in the atoms are tightly bound and unable to move between other atoms
the electrons are able to move freely between the different energy levels within the atom
their atoms can move freely between other atoms
their atoms are tightly bound in their shells, which makes them unable to move between other atoms

Answer 1

Answer: 2nd choice--electrons are able to move freely ...

Step-by-step explanation:

Metals are good conductors of electricity because at least 1 electron per metal atom is free, meaning it is not tied to any particular metal atom, but is able to move freely throughout the metal. Electrical current is the flow of electrons.
