Document Summary
Chemistry- a branch of physical science that studies the composition, (cid:1) structure, properties and change of matter (molecules) (cid:1) (cid:1) (cid:1) (cid:1) The periodic table reflects the law of chemical periodicity. The (cid:1) (cid:1) properties of the elements that will vary periodically with their atomic numbers include: (cid:1: meltingandboilingpoints, degreeofmetalliccharacter (cid:1, oxidizingorreducingproperties, atomicradius ionizationenergy, electronaffinity, ionsize, chargeofsimpleions, electronegativity (cid:1) (cid:1) (cid:1) (cid:1) group) (cid:1) (cid:1) (cid:1) Melting and boiling point dec. downwards except for the gasses (hydrogen and lithium in first. Some chemical properties typical for elements with metallic character: the more metallic the element, the more ionic character of its (cid:1) (cid:1) (cid:1) (cid:1) compounds with non metals (e. g. , magnesium chloride). (cid:1) (cid:1) hydroxides (e. g. , potassium oxide). (cid:1) (cid:1) (cid:1) Reactivity as an oxidizing or reducing agent: the more metallic the element, the more basic are its oxides and.
