Lesson Title: Today we are learning about
What is the electronic structure of an atom?
Remember to check for PROGRESS
Focus on Knowledge, Skills and Understanding
Success Criteria: You will show your learning by...
  1. The electrons in an atom occupy the lowest available energy levels (innermost available shells).
  2. The electronic structure of an atom can be represented by numbers or by a diagram. For example, the electronic structure of sodium is 2,8,1 or (electron arrangement using dot-and-cross diagram) showing two electrons in the lowest energy level, eight in the second energy level and one in the third energy level.
  3. (WS) Students should be able to represent the electronic structures of the first twenty elements of the periodic table in both forms.
  4. Students may answer questions in terms of either energy levels or shells.
  5. Atoms are very small, having a radius of about 0.1 nm (1 x 10-10 m).
Think about how you can match the needs of ALL students
Keywords:
  • Radius: the distance from the centre to the circumference of a circle or sphere. (1)
  • Group: a collection of elements found in the same column of the periodic table with similar properties. (1)
  • Atom: the smallest constituent unit of ordinary matter. (1)
  • Energy level: the shells that electrons are arranged into around the nucleus of an atom with the innermost shell being the lowest energy level. (1)

AFL/Key Questions:
  1. What is the maximum number of electrons that can be held by each of the three inner most shells?
    The maximum number of electrons are 2 in the inner most shell, 8 in the second shell and 8 in the third shell.
  2. What would a diagram of the electron structure of an atom of carbon look like?
    A diagram of the electronic structure of carbon would have 2 electrons on inner most shell, 4 on the second shell.
  3. Why is carbon found in group 4 of the periodic table?
    Carbon is found in group 4 because there are 4 electrons in its outermost shell.
  4. How big is the total radius of an average atom?
    The total radius of an average atom is 0.1 nm (1 x 10-10 m).

Starter Activity Differentiation and Challenge question/task
  • Students to copy and complete the keywords.
  • Teacher reveals missing letters; Students correct mistakes;
  • Discuss the scientific meanings of the words.
  • Students to write down the definitions of the most important / new keywords.
  • Discuss the 'Memory Anchor'.
    • What does it show?
    • How does it relate to the what we are learning about today (title)?
Think about PACE – Develop, consolidate and deepen knowledge, skills and understanding
