 * 2) Click on neutron and move it to the center of atom.
 * 3) Click on electron and distribute it to the orbits.
 * 4) Click on element name box to know the name of the element.
 * 5) Click on neutral/ion box to know whether the  atom is  neutral/ion.
 * 6) Click on stable/unstable box to know whether the  atom is  stable/unstable.
 * 7) Click on model options to see the structure of the entire atom.
 * 8) To know the mass number of the element  click on mass number.
 * 9) To know the net charge  of the atom  click on net charge.
 * 10) To know the period and group of the element click on element.

Developmental Questions (What discussion questions)

 * 1) How many orbits are there in  this atom?
