Lesson: The Structure of Atoms Chemistry • First Year of Secondary School

Students will be able to

• relate the size and scale of atoms to objects in the physical world to explain the incredibly small size of atoms,
• list the subatomic particles and their locations within the atom in order to describe the structure of the atom,
• recall the relative masses and charges of the subatomic particles to identify where areas of mass and charge occur within the atom,
• assess the combined charges of protons and electrons in order to determine the overall electrostatic charge of an atom.
