| Describe the structure of the atom. | An atom consists of a nucleus composed of protons and neutrons (collectively known as nucleons). This is orbited by electrons. |
| Give the relative charges of each of the particles in the atom. | Proton: +1 Electron: -1 Neutron: 0 |
| Give the relative masses of each of the particles in the atom. | Proton: 1 Electron: 1/1836 Neutron: 1 (The mass of a neutron is slightly greater than that of a proton). |
| What is the proton number of an atom? | The proton number (Z) of an atom describes the number of protons in the nucleus (!). |
| What is the nucleon number of an atom? | The nucleon number (A) of an atom describes the number of nucleons (protons + neutrons) in the nucleus (!). |
| What is specific charge and in what unit is it measured? | The specific charge of a particle or ion is the ratio of its charge to mass (Q/m). The unit, therefore, is C/kg (coulombs per kg). |
