Describe how alpha-particle scattering experiments provide evidence for: (a) a very small nucleus surrounded by mostly empty space (b) a nucleus containing most of the mass of the atom (c) a nucleus that is positively charged

Use decay equations, using nuclide notation, to show the emission of α-particles, β-particles and γ-radiation

Explain what is meant by an isotope and state that an element may have more than one isotope
