These particles, made up of protons and neutrons, are large and can only travel a short distance -- in fact, they can be stopped with just a piece of paper or even your skin. However, inhalation or ingestion of alpha particles can be very dangerous. Once inside your body, alpha ...
In the neutral, non-charged state, every atom has the same number ofelectronsas it does protons. Elements starting with helium also contain a number ofneutronssimilar to and usually slightly in excess of the proton number. Variants of elements with different numbers of neutrons are called isotope...
