1. Write the complete symbol, with numbers in the correct corners for an isotope of lithium that has a mass of 6 and a charge of +1.
2. How do the number of neutrons affect the stability/instability of an atom?
3. Allie hypothesized that if Atom “B” has 4 protons, 3 neutrons, and 4 electrons and atom C has 4 protons, 4 neutrons, and 4 electrons then B and C are isotopes. Try Allie’s atoms in the simulation. Explain why Allie’s hypothesis is correct or incorrect.
4. Rana hypothesized that if Atom “C” has 5 protons, 4 neutrons, and 7 electrons then “C” will be a positive ion. Try Rana’s atom in the simulation. Explain why Rana’s hypothesis is correct or incorrect.
5. Give a reason why each of the following symbols are incorrect
