Lesson Title: Today we are learning about
What are the size and mass of atoms?
Remember to check for PROGRESS
Focus on Knowledge, Skills and Understanding
Success Criteria: You will show your learning by...
  1. The relative electrical charges of the particles in atoms are: Proton +1 Neutron 0 Electron -1
  2. Atoms have no overall electrical charge.
  3. In an atom, the number of electrons is equal to the number of protons in the nucleus.
  4. The number of protons in an atom of an element is its atomic number.
  5. All atoms of a particular element have the same number of protons.
  6. Atoms of different elements have different numbers of protons.
  7. Students should be able to use the nuclear model to describe atoms.
  8. The radius of a nucleus is less than 1/10 000 of that of the atom (about 1 x 10-14 m).
  9. Almost all of the mass of an atom is in the nucleus.
  10. The relative masses of protons, neutrons and electrons are: Proton 1 Neutron 1 Electron Very small
  11. The sum of the protons and neutrons in an atom is its mass number.
Think about how you can match the needs of ALL students
Keywords:
  • Atomic number: number of protons found in an atom of an element. (1)
  • Neutron: a sub-atomic particle that has no overall charge found in the nucleus of an atom with a mass of 1. (1)
  • Electron: a negatively charged sub-atomic particle found in the electron shells (energy levels) of an atom with a negligible mass. (1)
  • Proton: a positively charged sub-atomic particle found in the nucleus of an atom with a mass of 1. (1)

AFL/Key Questions:
  1. What are the relative electrical charges of each sub-atomic particle?
    The relative electrical charges of each sub-atomic particles are: Proton 1 Neutron 0 Electron -1
  2. Why do atoms have no overall charge?
    Atoms do not have an overall charge as a number of POSITIVE protons will always match the number of NEGATIVE electrons.
  3. If an atom has 9 protons, how many electrons would it have?
    If an atom has 9 protons it would have 9 electrons.
  4. What does the atomic number of an element tell us?
    The atomic number tells us the number of protons found in an atom of that element.
  5. What do all atoms of a particular element have in common?
    Atoms of the same element all have the same number of protons.
  6. What are the differences between an atom of Nitrogen and an atom of Carbon. What is it that makes them unique elements?
    An atom of carbon has: Protons= 6 Electrons= 6 Neutrons= 6. An atom of Nitrogen has: Protons= 7 Electrons= 7 Neutrons= 7. It is the differing number of protons which makes them unique elements.
  7. How does the current nuclear model describe an atom?
    The nuclear model shows that an atom is made of a small nucleus of positive protons and neutral neutrons, it also has negatively charged electrons orbiting it in energy levels.
  8. How large is the radius of the nucleus of an atom in comparison to its total radius?
    The radius of the nucleus of an atom compared to the total atoms radius is 1/10 000 of that of the atom (about 1 x 10 to the power -14 m).
  9. Where is the majority of the mass of the atom found?
    The majority of the mass of the atom is found within the nucleus and is made up of protons and neutrons. Electrons have a negligible mass.
  10. What are the relative masses of each subatomic particle (proton, neutron and electron)?
    The relative masses of the subatomic particles are: Proton = 1 Neutron = 1 Electron = negligible (very small)
  11. What does the mass number of an atom tell us about that atom?
    The mass number tells us the total number of protons and neutrons within that atom.
