Understanding Atomic Structure: Key Concepts in Chemistry

This educational resource explores essential vocabulary related to atomic structure and subatomic particles, including protons, neutrons, electrons, atomic number, mass number, isotopes, energy levels, electron cloud, orbitals, and electron configuration. Students will engage in activities that deepen their understanding of atomic theory, including visual representations of atoms and calculations based on the periodic table. The resource includes interactive questions and practical examples, fostering a clear comprehension of how atomic components define elements and their identity.

  3. SPS1. Students will investigate our current understanding of the atom. • a. Examine the structure of the atom in terms of • Protons, electrons and neutron location • Atomic mass and atomic number • Atoms with different numbers of neutrons • Explain the relationship of the proton number to the element’s identity

  4. Bell Ringer • What are the three subatomic particles that make up atoms? What are the charges of each?

  5. Bell Ringer • Without using a book, draw your interpretation of an atom.

  6. Bell Ringer • Fill in the following information for Carbon 14 • Protons • Electrons • Neutrons

  7. Bell Ringer • Using the periodic table in a textbook, what is the atomic number and atomic mass/mass number for the following elements: • Nickel • Potassium • Silicon • How Many protons, neutrons and electrons does each have.

  8. Bell Ringer • I think I lost an electron, I better keep an ________ that. • Fill in the blank • Yes, you must copy the question.

  9. Bell Ringer • A neutron orders lunch and asks the waiter how much? • The waiter replies "no charge.“

  10. Bell Ringer • Why are He, Cm and Ba called the medical elements? • If you can't helium and you can't curium, there's nothing left to do but barium.

  11. Bell Ringer • What is the show cesium and iodine like watching together? • CSI
