- 2. Use a periodic table to help you identify each element. Give its symbol for the answer. 1. I am a member of the Boron family with 49 protons. 2. I have a total of 74 electrons in an atom. 3. I have an atomic mass of 55.847. 4. I have 8 neutrons in an atom. 5. I have 14 protons, 14 neutrons, and 14 electrons in an atom. 6. I have 99 protons and 99 electrons in an atom. 7. I am a member of the Halide family with 18 neutrons. 8. I have 20 neutrons, but only 2 valence electrons.
