The alkali metals are all shiny, soft, highly reactive metals at standard temperature and pressure and readily lose their outermost electron to form cations with charge +1. Representative reactions of alkali metals. They react vigorously, and often violently, with water to release hydrogen and form strong caustic solutions. They can all be cut easily with a knife due to their softness, exposing a shiny surface that tarnishes rapidly in air due to oxidation by atmospheric moisture and oxygen (and in the case of lithium, nitrogen). Lithium, sodium and potassium will all burn in air when heated to give the corresponding alkaline oxides (see below). When heated, lithium, sodium, potassium, rubidium, and cesium … Carbides. Group 1 metals are very reactive, and must be stored out of contact with air to prevent oxidation.

The rate of reaction with oxygen, or with air, depends upon whether the metals are in the solid or liquid state , as well as upon the degree of mixing of the metals with the oxygen or air. This produces a layer of dull oxide on the surface of the metal, called tarnish. (Lithium also reacts with nitrogen.) Why are alkali metals stored in oil? Most common nonmetallic substances such as halogens, halogen acids, sulfur, and phosphorus react with the alkali metals. This is important as elements in the same group will react similarly. and are stored under

Halogens such as chlorine, bromine and iodine have properties that enable them to react with other elements to form important salts such as sodium chloride, also known as table salt.
Reactions of alkali metals with water All the alkali metals react vigorously with cold water. Due to formation of film of oxides of beryllium and magnesium, they do not continuously react with oxygen. When heated alkali metals are placed into jars of oxygen gas, they will burst into flames. Watch the two largest alkali metals react with the airFrom the Peter Wothers lecture series - The Alkali Metals Group 1 metals react with oxygen gas produces metal oxides. They all react quickly with oxygen in air, and with water. A similar reaction takes place with the other elements of group 7. The Alkali Metals - Reaction with Oxygen (burning in air).
The alkali metals react readily with atmospheric oxygen and water vapour. The reactions of the Group 2 metals with air rather than oxygen is complicated by the fact that they all react with nitrogen to produce nitrides. The Reactions with Oxygen. The alkaline earth metals all react with the halogens to form ionic halides, such as calcium chloride (CaCl 2 ), as well as reacting with oxygen to form oxides such as strontium oxide ( SrO ). Metals reacting with nitric acid, therefore, tend to produce oxides of nitrogen rather than hydrogen gas. In each reaction, hydrogen gas is given off and the metal hydroxide is produced. Lithium is unique in Group 1 because it reacts with nitrogen in the air as well as oxygen. GCSE Physics. The general equation for this reaction is: metal + oxygen → metal oxide. + oxygen
