Explain the main structures of an Atom.
Hello today I'm going to tell you about the main structures of an atom, but first I'm going to tell you what an atom is, a atom is the basic unit of an element. First off I'm going to tell you about protons, protons have an electric charge, their electric charge is positive, the number of protons in the nucleus of an atom determines the atomic number of that atom for example if you the element Ne (Neon) has 10 protons, protons have a charge that equal to +1, to find the mass of a proton you would use 1.6726 x 10^-7. Next I'm going to tell you about a neutron, a neutron has a neutral charge, if an atom has a equal number of protons and electrons then it cancels the charges and becomes neutral, neutrons are located in the nucleus with the protons, but during radioactive decay they can be knocked out of the nucleus, every element that has atoms contains neutrons except for one hydrogen, Last is electrons, electrons have a negative charge, all the electrons create a negative charge which helps balance the positive charge of the protons in the nucleus, they are found in clouds that surround the nucleus. That's all I have for you today, Bye!
