Exceptions to its predictions arise, however, when very active metals react with oxygen, which is one of the most reactive nonmetals. Many metals react with oxygen gas to form the metal oxide. a metal is: the more vigorous its reactions are; the more easily it loses electrons in reactions to form positive ions (cations) The table summarises some reactions of metals in the reactivity series. Potassium and sodium are soft metal which are easily cut exposing a shiny surface which changes to dull rapidly. The familiar red form of rust is (Fe 2 O 3 ), but iron has other oxidation states, so it can form other colors of rust. When a metal reacts with oxygen, a metal oxide forms.

Most common nonmetallic substances such as halogens, halogen acids, sulfur, and phosphorus react with the The peroxides and superoxides are potent oxidants. Lithium, sodium and potassium form white oxide powders after reacting with oxygen. These oxides differ from metallic oxides because they are acidic in nature. A method to do this is to count on there is a confined supply of one reactant and an unlimited deliver of the opposite. With the help of equations, explain the reaction of non-metals with oxygen. Oxides typically react with acids or bases, sometimes both. The reactions with oxygen. Potassium and sodium are soft metal which are easily cut exposing a shiny surface which changes to dull rapidly.

All the alkali metals react directly with oxygen; lithium and sodium form monoxides, Li 2 O and Na 2 O, and the heavier alkali metals form superoxides, MO 2. For example, calcium reacts as follows: You wish to calculate the mass (g) of calcium oxide that can be prepared from 4.20 g of Ca and 2.80 g of O 2. The reactions are the same in oxygen and in air, but oxygen will generate a more violent reaction. Exceptions to its predictions arise, however, when very active metals react with oxygen, which is one of the most reactive nonmetals. The alkali metals react readily with atmospheric oxygen and water vapour. (Lithium also reacts with nitrogen.)
