There are several checkbox items in the 'Show' box at the bottom of the simulation; uncheck all of these boxes for
now. Then, click and drag sphere from the 'Protons' bucket and move it to the center of the atom, then move one electron to the first shellof the atom. In the box below, explain any changes being sure to note the name and charge of the element.
Predict what would happen if add an electron to your newly created atom. Give your prediction
Was your prediction correct? If not, explain how your prediction deviated from the what you observed.
Play with the simulation as you did in the previous steps to determine which particle(s) give(s) rise to the name of the element that you build. Which particle determines the name of the element?
