Phase Change Diagram

  • What are the parts of a phase change diagram
  • What is occurring in each part of the diagram with respect to temperature and heat?

Atomic structure

  • What are the three subatomic particles
  • Compare and contrast the subatomic particles in terms of location, charge and mass
  • Identifying atoms based on structure and the periodic table
  • Use the periodic table to determine an atom’s atomic #, atomic mass, mass #, # protons, neutrons and electrons
  • Determine the total charge of all of the protons and electrons in an atom

Periodic Table

  • Identify the group by nameto which an element belongs (i.e. alkali metals, etc.)
