Lesson Plan: Isotopes Physics

Start Practising

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to work out the number of protons, neutrons, and electrons an atom of an isotope has from its chemical symbol.

Objectives

Students will be able to

define an isotope,
calculate the number of protons, neutrons, and electrons for an atom of an isotope,
recall some of the common isotopes of carbon,
identify isotopes of an element from their chemical symbols.

Prerequisites

Students should already be familiar with

chemical symbols and formulas,
the structure of the atom,
atomic number and mass number.

Exclusions

Students will not cover

using isotopic abundances to calculate average atomic mass,
uses of isotopes.
