Chemistry Paper 1 Keywords - Atomic Structure
Cards in this deck (20)
- 1Atomthe smallest quantity of an element that can take part in a chemical reaction, consisting of a positively charged nucleus made up of protons and neutrons, surrounded by negatively charged electrons
- 2Elementa substance made of only one type of atom
- 3Compounda substance containing atoms of two or more elements, which are chemically combined in fixed proportions
- 4Equationa scientific statement that uses chemical names or symbols to sum up what happens in a chemical reaction
- 5Reactantsthe substances that react together in a chemical reaction
- 6Productsthe substances produced in a chemical reaction
- 7Mixturea combination of two or more elements, which are not chemically combined together
- 8Filtrationseparation techniques used to separate insoluble solids from solids
- 9Crystallisationtechnique used to obtain a soluble solid from a reaction
- 10Simple Distillationtechnique used to separate a substance from a mixture due to a difference in boiling points
- 11Fractional Distillationa separation technique used to separate mixtures which contain components with similar boiling points
- 12Chromatographya separation technique used to separate the coloured components of a mixture
- 13Electrona sub-atomic particle which has a negative charge , small relative atomic mass and which orbits the nucleus
- 14Protona sub-atomic particle with a positive electric charge, equal to that of an electron. forms part of the nucleus of the atom
- 15Neutrona sub-atomic particle with no electric charge. About the same mass as a proton and also forms part of the nucleus of the atom
- 16Atomic Numberthe number of protons in a given atom, which determines the element and gives its place on the periodic table
- 17Mass Numberthe total number of protons and neutrons in a nucleus
- 18Isotopeeach of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties; in particular, a radioactive form of an element
- 19Ionan atom or molecule with a net electric charge due to the loss or gain of one or more electrons.
- 20Electron Configurationthe distribution of electrons in an atom, in atomic or molecular orbits
