The change in chemical properties of oxides change from left to right across a period and from top to bottom within a particular group has to be determined. Concept Introduction: According to physical and chemical properties, the elements can be further divided into metals, non-metals and metalloids. In a group, the metallic character of an element increases from top to bottom whereas in a period, it decreases from left to right. The classification elements in the periodic table as metals, nonmetals, or metalloids can be given as Oxide is the compound formed when oxygen reacts with another element. Oxides formed with metals are basic Oxides formed with metals are basic. Most of oxides formed with nonmetals are acidic. Amphoteric oxides have the properties of bases and acid. Elements that are in the intermediate position of periodic table form amphoteric oxide.
