To determine

The reason for atoms of a conductor usually contains valence electrons.

Expert Solution & Answer

Explanation of Solution

Conductors are formed from materials which have large and heavy atoms. Most of materials which conducts are metals. Conductors are formed from the atoms which usually have one or more electrons in their valence shell.

An atom with only one valence electron is the best electrical conductor because of the loosely held electron orbit and it can be easily abandoned for current flow. Thus the conductors have electrons with one or two electrons in the valence shell.
