- C1 1.2 Atomic structure
- Atoms contain protons, neutrons and electrons
- Protons and Neutrons are found in the nucleus
- Electrons orbit the nucleus
- Proton has a relative charge of +1(positive) and a relative mass of 1
- Neutron has a neutral relative charge (0) and a relative mass of 1
- Electron has a relative charge of -1(negative) and a relative mass of 0
- Any atom contains equal numbers of protons and electrons
- Atomic number
- The atomic number is the number of protons in the nucleus
- The periodic table is arranged in order by atomic number
- Mass number
- The mass number is the number of protons plus neutrons
- Number of neutrons= Mass number - Atomic number
- Atoms contain protons, neutrons and electrons
