&information1=This tool allows you to build your own atom. Drag the electrons, neutrons or protons onto the atom. The elecrtons will only stay in the outer shells. The protons and neutrons will only stay in the nucleus.
Check the box at the bottom to only add a new shell when the previous one has been filled. Uncheck this box if you wish to display all three shells.
Press "reset" to start again.
This is a simplified version of the electron shells. This simulation only goes up to the first three shells.
