Atom icon.
a. Pick any one of the first 10 elements that you would like to build and state its symbol.
b. Drag protons, neutrons, and electrons onto the atom template to make an atom of your element.
State the numbers of protons, neutrons, and electrons in your atom, as well as the net charge and mass number.
c. Click on 鈥淣et Charge鈥 and 鈥淢ass Number,鈥 check your answers to (b), and correct, if needed.
d. Predict whether your atom will be stable or unstable. State your reasoning.
e. Check the 鈥淪table/Unstable鈥 box. Was your answer to (d) correct? If not, first predict what you can do to make a Stable atom of your element, and then do it and see if it works. Explain your reasoning.
