What is its charge? 5. What is a neutron and where is it located in an atom? What is its charge? 6. How do you determine the amount of protons, neutrons and electrons an atom has? 7. An atom has 17 protons. Which atom is it? (Hint, use the periodic table on page 154 in the Intro to Matter book). How many electrons does it have? 8. What is atomic mass? Atomic number? 9. Lithium has an atomic mass of 7 atomic mass units and an atomic number of 3. How many neutrons does Lithium have? 10. Draw a Bohr’s model of Sulfer. You may use a periodic table. 11. The periodic table has two main patterns with the number and placement of electrons. What are they?
