You are watching: How to make an atom model with styrofoam balls
Paint 10 of the 1-inch styrofoam balls v the red paint, using a foam brush. Wash the foam brush and also paint the continuing to be 1-inch balls v the yellow paint. To wash the foam brush again, and paint the 10 little styrofoam balls with the blue paint. Leaving the balls to dry.
Use the black color marker to compose a plus sign on the red balls and a minus sign in the blue balls. This represents the confident charge top top the protons and the an unfavorable charge ~ above the electrons.
Place one finish of a toothpick in a red ball and the other end in a yellow ball. Push the balls along the toothpick until they"re nearly touching. Location a dab of glue on one sphere where the various other will touch it, then push the balls completely together. Organize them in place until the glue is set.
Place the finish of one more toothpick in one of these balls and also attach one more ball in the exact same way. Perform this until all the balls attach in a spherical shape, mix the red and also yellow balls randomly. This is the cell nucleus of the atom, consist of of protons and also neutrons.
Push one end of the 23-inch item of wire v the facility of 2 blue balls. Measure 3 inches native one finish of the wire and bend the quick piece at best angles come the rest of the wire. Loop the much longer piece that wire into a circle and also check the it fits over the atom nucleus. Change the loop if that is as well small. Near the wire circle by twisting the complimentary end roughly the finish of the circle number of times. Girlfriend will have actually a loop of cable holding two blue balls v a short piece of wire pointing in the direction of the facility of the circle.
Place the loop end the nucleus and push the brief end piece into the nucleus. Relocate the two balls so the they room directly throughout the loop from every other. The two blue balls, electrons, should show up in orbit roughly the nucleus at a street of about 2 inches.
Push one end of the 30-inch piece of wire through the center of the remaining eight blue balls. Measure 6 inches native the finish of the wire and also bend the short piece at ideal angles to the remainder of the wire. Loop the longer piece right into a circle and also check the it fits over both the nucleus and the first wire loop. Readjust the cable circle come fit. Nearby the loop by twisting the end of the wire roughly the finish of the circle.
Place the loop over the nucleus and the an initial loop so the it is at an edge to the first loop. Press the free end of the wire right into the nucleus. Move the eight blue balls so that they room evenly spaced approximately the loop.

use colored pompoms in ar of the styrofoam balls if they room unavailable.
The styrofoam balls deserve to be of any colors as long as you use various ones for the protons, neutrons and electrons.
You have the right to adapt these instructions to make any kind of atom, as lengthy as you recognize the variety of protons, neutrons and electrons it contains.

use colored pompoms in place of the styrofoam balls if they space unavailable. The styrofoam balls deserve to be of any type of colors as long as you use different ones for the protons, neutrons and electrons. You have the right to adapt this instructions come make any type of atom, as long as you understand the variety of protons, neutrons and also electrons that contains.
