CHAPTER 4: Inside the Atom
Science Understanding
• Describe and model the structure of atoms in terms of the nucleus, protons, neutrons and electrons
• Describe the differences between protons, neutrons and electrons
• Describe the three types of radiation released by unstable atoms – alpha and beta particles and gamma radiation
• Describe and distinguish between chemical and nuclear reactions in terms of conservation of mass
• investigating the effects on humans of exposure to electromagnetic radiations such as X-rays and microwaves
Science as Human Endeavour
• Investigate the historical development of models of the structure of matter
• Reflect on how knowledge about nuclear fission was used to develop the atomic bomb

Flame Colours PracticalWhy do different metal salts produce a different colour?
Each element has a different number and arrangement of electrons. As we add energy, they jump to a different shell. When returning to their original position, they release this energy as a specific colour

Nuclear Reactions Vs
Chemical Reactions involve the electrons. Nuclear Reactions involve the nucleus.
Nuclear Fission is the splitting of an atom - it can be uncontrolled (like an explosion) or controlled (like in a power station)
