  1. CHEMISTRYOCTOBER 20, 2014 ATOMIC CONCEPT ATOMIC NUMBER AND MASS NUMBER

  2. SCIENCE STARTER • You are seated and quiet • You have 2 minutes • Do the SCIENCE STARTER

  3. AIM • How do we read the periodic table?

  4. PUZZLES • Using the Periodic Table, solve the puzzles. You are given 10 minutes. • You may work with a partner. Both partners must be actively participating. I will be walking around grading you on your participation. • Stop when you see the stop sign

  5. DEBRIEF • So, what is the atomic number? • How did you know where to find it? • How did you know what is the number of protons? • How did you know what is the number of electrons?

  6. VOCABULARY • ATOMIC NUMBER • MASS NUMBER • ATOMIC MASS • ATOMIC MASS UNIT • PERIODIC TABLE

  7. ATOMIC NUMBER • the number of protons that an atom has in its nucleus

  8. MASS NUMBER • number of neutrons and protons in an atom for an element

  9. ATOMIC MASS • weighted averagemass of an atom of an element based on the relative abundance of that element’s isotopes

  10. ATOMIC MASS UNIT • unit for atomic mass

  11. PERIODIC TABLE • a table of the chemical elements arranged in order of atomic number, usually in rows, so that elements with similar atomic structure (and hence similar chemical properties) appear in vertical columns.

  12. One atomic mass unit • 1/12 of the mass of a carbon atom that contains 6 protons and 6 neutrons

  13. AMU • Proton = 1 amu • Neutron = 1 amu • Electron = 0 amu (almost zero so do not count)

  14. READING THE PERIODIC TABLE

  15. READING THE PERIODIC TABLE • Element = Carbon • Symbol = C • Atomic Number = 6 • Atomic Mass = 12.0107 amu • Mass Number = 12 • Number of Protons = 6 • Number of Electrons = 6 • Number of Neutrons = 6

  16. TRY IT
