This highway is made up of billions of nerve cells, or neurons which join together to make nerves. This is very important for the human to be able to live!</span>
Answer:
The opposite charges of the atoms hold the atoms together. One atom can have a positive charge while the other can have a negative charge and this causes an electrostatic attraction causing the atoms to stick to each other like glue. For example, two magnets, can only be attracted to each other when one side of the magnet has a "-" while the other magnet on one side has a "+". They are attracted to each other by these varying charges. The same applies to ionic compounds which are held together by the varying charges of the ions.
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.
