Build an Atom
This virtual lab allows you to build an atom out of protons, neutrons and electrons and see how the element and the mass changes.
.
Very good virtual lab that allows the user to use the number of protons, neutrons, and electrons to draw a model of the atom, identify the element, and determine the mass and charge. It also allows the user to predict how addition or subtraction of a proton, neutron, or electron will change the element, the charge, and the mass
