Physics

In a crystal of salt there are electrons and
positive ions.
How does the net charge of the electrons
compare with the net charge of the ions?
1. Unable to determine
2. Sometimes the net charge of the negative
electrons is greater than the net charge of the
ions and sometimes it is less.
3. The net charge of the negative electrons
is less than the net charge of the ions.
4. The net charge of the negative electrons
is greater than the net charge of the ions.
5. The net charge of the negative electrons
has the same magnitude as the net charge of
the ions.
