I know that O 3 is ozone and is toxic. Grab a drink, sit down, and try to follow along. First of all, we need to understand something about atomic structure. Protons are positively charged particles and neutrons have no charge, giving the nucleus an overall positive charge.
Electrons have a negative charge.
In an atom with an overall charge of zero, there are as many electrons as protons. Stay awake, the answer's coming up. The number of protons determines what element an atom is. If we could somehow add a proton to a nucleus, we'd change the atom into a different element. For example, carbon, familiar to us in the form of graphite and diamonds, has twelve protons.
