	The atom is composed of protons, neutrons and electrons. These particles are all very tiny, on the scale of nanometers. To give an idea of how small a nanometer is, we have a million dot book. Each dot is only one millionth of the book, which means each dot is pretty small. If we split each dot into a thousand more dots, then each of those dots would be one billionth of the book! A nanometer is one billionth of a meter, which is really, really small!

	~~The number~~ of ~~protons in an atom determines what element that atom~~ is. ~~If we use only one proton~~, ~~that would be hydrogen. If we use six, that makes it carbon. However, it is really hard to get six protons to stick together, because protons have~~ a ~~positive charge, and like charges repel. That's where neutrons come into play; they have~~ a ~~neutral charge~~, so they can connect to protons. They help to keep those protons together for bigger elements. We can adjust the number of neutrons that are in an element, which changes how the element interacts with other elements. Each type of an element with a ~~different number of neutrons is known as an~~ ''~~isotope~~''~~, and some isotopes are more stable than others~~. ~~For example, Carbon-12~~ is ~~stable~~, ~~and is~~ the ~~carbon we usually see~~, ~~with six protons and six neutrons~~. ~~Carbon-13 has~~ one ~~extra neutron~~, and ~~is what we use for Carbon Dating, a method~~ to ~~figure out how old something is~~!		All of matter is composed of ''Atoms''. Atoms are very small building blocks, smaller than a billionth of a meter, or a ''nanometer''. To get how small this is you can reference the million dot book which, as the title says, has a million dots inside of it. You would need a thousand of those books to get to one billion dots, and even at that point you would have to split each dot into three pieces to get to the scale of atoms!

	~~Electrons are smaller than protons~~ and ~~neutrons, and are not in the atom itself~~. ~~They~~ have a ~~negative~~ charge, and ~~float around~~ the ~~atom because~~ of ~~the positive charge on the~~ protons. If ~~an atom has a charge to it~~, we ~~call~~ it ~~an ''ion''~~. ~~If it lacks electrons~~, it ~~has~~ a positive charge, and is ~~called a~~ ''~~cation~~''. ~~If it~~ has extra ~~electrons~~, ~~it has~~ a ~~negative charge, and~~ is ~~called an ''anion''.~~		An atom's nucleus is composed of two things: ''Protons'' and ''Neutrons''. Protons have a positive charge, and the number of protons in an atom determines what element that atom is. If we use only one proton, that would be hydrogen. If we use six, that makes it carbon. However, it is really hard to get six protons to stick together; protons have a positive charge, and like charges repel. That's where neutrons come into play; neutrons have a neutral charge, so they can connect to protons. They help to keep those protons together for bigger elements. We can adjust the number of neutrons that are in an element, which changes how the element interacts with other elements. Each type of an element with a different number of neutrons is known as an ''isotope'', and some isotopes are more stable than others. For example, Carbon-12 is stable, and is the carbon we usually see, with six protons and six neutrons. Carbon-13 has one extra neutron, and is what we use for Carbon Dating, a method to figure out how old something is!

			Electrons are smaller than protons and neutrons, and are not in the atom itself. They have a negative charge, and float around the atom because of the positive charge on the protons. If an atom doesn't have an equal number of protons and electrons, then it will have a charge, and we would call it an ''ion''. If it lacks electrons, it has a positive charge, and is called a ''cation''. If it has extra electrons, it has a negative charge, and is called an ''anion''.

			This demonstration is an engaging approach on talking about the parts of the atom. With younger students you can discuss the basics of the parts of the atom and how elements are made, while with older students you can talk more about the charge of the atom, Anions and Cations, and isotopes!

		The atom is composed of protons, neutrons and electrons. These particles are all very tiny, on the scale of nanometers. To give an idea of how small a nanometer is, we have a million dot book.

A nanometer is one billionth of a meter, which is really, really small!

		The number of protons in an atom determines what element that atom is. If we use only one proton, that would be hydrogen. If we use six, that makes it carbon. However, it is really hard to get six protons to stick together, because protons have a positive charge, and like charges repel. That's where neutrons come into play; they have a neutral charge, so they can connect to protons. They help to keep those protons together for bigger elements.
