However as the number of protons increases, more neutrons are needed to keep the nucleus stable. , ie an atom with six protons in its nucleus will always be carbon, and uranium will always have 92 protons. An atoms nucleus can only be stable if it has a certain amount of neutrons for the amount of protons it has. It covers the areas of the Physics foundation paper. - OCR 21st Century, How can radioactive materials be used safely? A nucleus will regain stability by emitting alpha or beta particles and then cool down by emitting gamma radiation. The number of protons is what defines the element, ie an atom with six protons in its nucleus will always be carbon, and uranium will always have 92 protons. However, the number of electrons will change if the atom becomes, What is radioactivity? For example carbon, carbon-12 is stable and has six protons and six neutrons. Atoms are very small, they have a radius of around 1 10, Protons and neutrons are the heaviest particles in an atom and as a result they make up most of the. Atoms are very small, they have a radius of around 1 1010 metres. Our tips from experts and exam survivors will help you through. For example lead, lead-206 has 82 protons and has 124 neutrons. This GCSE BBC Bitesize video is from the original programmes from 2000 that were broadcast on BBC2. GCSE Combined Science Radioactivity learning resources for adults, children, parents and teachers. The mass of electrons is often not considered to be significant. Each particle has its own charge and its own mass. GCSE Physics (Single Science) Radioactivity learning resources for adults, children, parents and teachers. An atoms nucleus can only be stable if it has a certain amount of neutrons for the amount of protons it has. Read about our approach to external linking. The total number of protons and neutrons is called the, In a neutral atom, the number of electrons is always the same as the number of protons. Protons and neutrons are the heaviest particles in an atom and as a result they make up most of the mass of the atom. Nuclei with too many, or too few, neutrons do exist naturally but are unstable and will decay by emitting radiation. For example lead, lead-206 has 82 protons and has 124 neutrons. For example carbon, carbon-12 is stable and has six protons and six neutrons. When nuclei are unstable they may emit ionising radiation to become more stable. can only be stable if it has a certain amount of, Elements with fewer protons, such as the ones near the top of the.
