This resource is a fully differentiated lesson aimed at teaching the Physical Sciences and focuses on isotopes of elements, and calculating Proton, Electron and Neutron values.

There are 4 learning objectives in the IDEAL format:

  • Identify the mass and atomic numbers of an element.
  • Describe that for an element there are equal numbers of protons and electrons, and use this to calculate the numbers of protons, neutrons and electrons for an element.
  • Explain that atoms of the same element can have different numbers of electrons and neutrons.
  • Apply your ideas of atomic structure to calculate more difficult proton, electron and neutron values for an ion and/or isotope.

This lesson is designed with a challenge questions throughout to stretch your most able students, whilst detailed slides help with dual coding to support all students.

Review the lesson before teaching to see how the animations and objectives will work in your lesson.
