Carbon has an atomic number of 6. This means it has 6 protons and 6 electrons. How many valence electrons does carbon have?

4

Explanation:

Carbon configuration- 2,4

Valence electrons means the outershell electrons

That means valence electrons=4

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
