Question

Good conductors have many loosely bound
A. Atoms
B. Protons
C. Molecules
D. Electrons

Answer 1

Hint: There three types of substances are present in nature as per the concept of the conductance. There are conductors, semiconductors and insulators. They are classified according to the property of the conductance.

Complete answer:
- In the question it is given that to find the reason for the behavior of the good conductors.
- Conductors are the substances which allow the heat and electricity very easily to pass through it.
- All the substances in nature are not good conductors.
- The substances which won’t allow the flow of electricity or heat through them are called insulators.
- The substances which are not conductors but are going to act as conductors by increasing the temperature are called semiconductors.
- The reason behind the substances which are going to act as good conductors is due to the presence of the loosely bound electrons.
- The loosely bound electrons will easily move in the substance and allow the electricity or heat to pass through it.
- Therefore, good conductors have many loosely bound electrons.

So, the correct option is D.

Note:
The loosely bound electrons will move easily in between the atoms of the substance and will cause the electricity or the heat to pass through the substance and make the substance to act as a good conductor. Mostly all the metals have loosely bound electrons and they are going to act as a good conductor.
