- 1atomsparticles of which all matter is made
- 2NucleusDense central region of an atom
- 3ProtonPositively charged sub-atomic particle found in the nucleus
- 4NeutronUncharged sub-atomic particles found in the nucleus
- 5Electronnegatively charged sub-atomic particle found outside the nucleus
- 6electron cloudRegion around nucleus where nucleus where electron are likely to be found
- 7Chemical SymbolEach element has a unique one
- 8Atomic NumberNumber of protons in the nucleus of an atom
- 9Mass NumberNumber of protons and neutrons in the nucleus of an atom
- 10Nuclear forceforce that binds neutrons and protons together in the nucleus
- 11IsotopesAtoms of an element with varying number of neutrons
- 12Relative Atomic MassMean mass of an element taking into account isotope abundance
- 13Periodic TableChart of elements arranged according to increasing atomic number
- 14Electron ConfigurationArrangement of electrons around the nucleus in energy levels
- 15light spectrumdifferent wavelengths of light admitted by an excited atom
- 16Energy LevelRegion around nucleus containing electrons with equal energy
- 17ElementSubstance made of atoms with the same number of protons
- 18Allotropesa different physical form of the same element
- 19Absorption Spectroscopytechnique to determine the concentration of an element
- 20electrostaticattraction between oppositely charged objects
- 21Difference between an atomic number and a mass numberatomic number is the number of protons in the nucleus whereas the mass number is the number of protons AND neutrons in the nucleus
- 22Difference between isotopes and allotropes of an elementan allotrope is a different form of the same element whereas an isotope is different forms of an element with the same number of protons but different number of neutrons
- 23Difference between a period and a group of the periodic tablegroups give information about the number of valence electrons and trends between atoms whereas periods give information about the number of energy levels occupied by electrons in an atom
- 24Difference between atomic absorption spectroscopy and mass spectrometryAtomic absorption spectroscopy determines the unknown whereas mass spectroscopy uses different masses of particles to measure their relative abundance in a sample
