A planetary model of a nitrogen atom could look something like this: Having the right number of electrons is usually good enough. Depending on your teacher, the actual orbits usually don't matter. In it, the electrons are said to orbit the nucleus much like the planets in the solar system orbit the sun. This model is typically taught to younger students as an introduction to atomic structure. This model depicts an earlier view of the structure of the atom, shortly after the nucleus was discovered. How you place them depends on which model of atomic structure your class is studying. The electrons are found outside the nucleus. For nitrogen, the nucleus would look something like this: All of your atom's protons and neutrons go in the nucleus. The nucleus, the central part of the atom, is made from protons and neutrons. It is also helpful if the electrons are smaller than the protons and neutrons. It is helpful if the balls are color coded so that it is easier to tell which balls are protons, which are neutrons and which are electrons. Basically, anything that is roundish and that can be glued to each other should work. Ping-pong balls, rubber balls, ball bearings, golf balls and styrofoam balls have all been used in the past. Now that you know how many protons, neutrons and electrons you will need for your model, it is time to decide what to use to represent them. Using information found on the Periodic Table of Elements, we can tell that an average atom of nitrogen contains 7 protons, 7 neutrons and 7 electrons.

If you do not already know how to use the Periodic Table of Elements to find this information, read the ' How many protons, electrons and neutrons are in an atom of.?' page to learn how. Do you need to make a model or a drawing of an atom for science class? If so, follow these instructions to learn where all of the atom's pieces go.īefore you can build your model, you will need to know how many protons, neutrons and electrons your atom has.
