6. What determines the identity of an element? the number of protons 7. Test your idea by identifying the element for the 3 cases. Insert captured images. What Element is it? example 1 2 Page 3 3 Atom or Ion has #of protons: 6 #of neutrons: 7 #of electrons: 7 8. What does the tool called Symbol tell you about what parts are in an atom or ion? #of protons: 6 # of neutrons: 6 #of electrons: 6 Remove a neutron # of protons: 7 # of neutrons: 6 # of electrons: 6 9. What rules can you use to tell how many protons, neutrons and electrons make up an atom or ion? Test your understanding: Open the full simulation Build an Atom 10. Using all the rules you have determined, figure out what is different for each of these changes to an atom or ion. If you have new ideas, go back and rewrite your rules. Make the change: What changes? Element name, charge, mass? Add a proton
