These are the fundamental units that build up all matter. The chemical composition of engineering material indicates the elements which are combined together to form that material. 5.2 Chemical properties of the groups (ESABP) In some groups, the elements display very similar chemical properties and some of the groups are even given special names to identify them. Each column is called a group. The properties of ceramic materials, like all materials, are dictated by the types of atoms present, the types of bonding between the atoms, and the way the atoms are packed together. Uses and properties John Emsley, Nature’s Building Blocks: An A-Z Guide to the Elements, Oxford University Press, New York, 2nd Edition, 2011. (c) Hydrogen gas is very flammable. Modern periodic law: The Modern periodic law states “The chemical and physical properties of elements are a periodic function of their atomic numbers”. 0. Properties of the elements One useful way of describing the chemical elements is according to their metallic or nonmetallic character.

T. L. Cottrell, The Strengths of Chemical Bonds, Butterworth, London, 1954. Group and Electron Configuration The group (column) of the periodic table determines the valence electron count. The chemical properties are determined by the number of electrons in the outer shell of the atom. The chemical properties of an element are determined by the configuration of its electrons in orbit around its nucleus. The number of electrons in orbit is equal to the number of protons in the nucleus (each proton has an an electrical charge of plus one, while each electron has the same charge only negative one). b. period. A chemical property is a characteristic or behavior of a substance that may be observed when it undergoes a chemical change or reaction. Chemical properties are seen either during or following a reaction since the arrangement of atoms within a sample must be disrupted for the property to be investigated.
