What is a conductor/insulator?

and how do they work?

A conductor is a object that allows an electrical current to pass through it. An insulator does not let electrical currents pass through it but protect other objects from the electrical current. Conductors work to move currents to other spaces and Insulators work to minimize the transfer of heat energy.

Because electrons have negligible mass, to account for the mass of the isotope, there must be 16 neutrons, 16 neutrally charged, massive, fundamental particles present in the sulfur nucleus. and thus finally, if we have the 32s2− ion, there are 18 electrons, 16 protons, and 16 neutrons.

Okay this will take 1 hour okay dont forget me.
