Build your own atom and learn about atomic structure and particles.

To Do

• Recall the definition of proton, neutron, electron, atom, and ion.
• Use the number of protons, neutrons, and electrons to draw a model of the atom, identify the element, and determine the mass and charge.
• Predict how addition or subtraction of a proton, neutron, or electron will change the element, the charge, and the mass.
• Use the element name, mass, and charge to determine the number of protons, neutrons, and electrons.
