Brief Summary of Unit
Students will understand that:
• Atoms are composed of three subatomic particles, the location of each, and their atomic charges.
• The atomic mass and the atomic number are directly related to their position on the periodic table and the number of subatomic particles.
• Atoms are classified/identified by the number of protons (atomic number).
• The arrangement of the periodic table reflects the structure, behavior, and mass of the element.
• What are the subatomic particles that compose an atom? Where are they located?
• How are atoms classified?
• What is the importance of valence electrons?
• How was indirect evidence used to create a model of the atom?
• How does the atomic mass and the atomic number relate to their position on the Periodic Table and the amount of the subatomic particles?
• How are isotopes unique?
• How is a Periodic table organized?
• What does the arrangement of the Periodic Table reflect?
Students will know: (Knowledge)
• Terms related to atoms and the Periodic Table.
• Atoms are comprised of protons, neutrons, and electrons. Each subatomic particle has it’s own electric charge.
• Determine the number of subatomic particles by the atomic number and atomic mass.
