![]() For example, sodium chloride (table salt) and sodium carbonate (soda ash) are widely available sodium compounds. Since alkali metals react readily, they are usually found in conjunction with other metals in nature. ![]() So, all of the alkali metals like to make cations that have a charge of +1." Alkali Metals in Nature When this happens, the atom is referred to as an ion and since it would have a positive charge, it is called a cation. "As electrons have a charge of -1, losing an electron causes the atom to have a charge of +1. Chip Nataro, chemistry professor at Lafayette College in Easton, Pennsylvania. All of the alkali metals like to give up their single valence electron," says Dr. In this process, the alkali metal is said to be oxidized, and whatever takes the electron from the alkali metal is reduced. "Since the alkali metals only have one valence electron, they typically achieve this state by giving up that electron. That's why chemists talk about atoms wanting to achieve a "noble gas configuration." Noble gases (elements like neon and helium) are not very reactive because their outermost electron shells are full. In fact, reactivity in chemistry is defined by the number of electrons in the outermost shell. When the hydroxide reacts with carbon dioxide to carbonate.Having only one valence electron in the outermost shell makes it very easy for the alkali metal atoms to reach points of stability - they just need to lose one electron! This willingness and ease of losing an electron to reach a state of equilibrium is known as high reactivity. ![]() The metals & their oxides react with water to yield hydroxides Due to their ionic nature, they form conducting solutions. If we expose an alkali metal to a halogen then it will cause an extremely exothermic reaction & as result, we get ionic salt. The hydrogen that is released is gaseous hydrogen and it is flammable.ĢMs+2H 2O→2MOHaq+H 2g Reaction with Halogen The metal of pure alkali metal is basic anhydride. The alkali metal can directly react with water if it is a pure alkali metal. Then the hydroxide of these elements dissolved completely in water and form some strongest bases like Sodium Hydroxide. When oxide reacts with water, it reacts vigorously and forms a hydroxide. They are less reactive than pure metals.ĤMs+ O 2g→ 2M 2O The reaction of oxide with water Oxide has a dull appearance and its reactivity is low. Here we are listing some reaction equations of alkali metals Reaction with oxygen Francium is used in research because it is one of the rarest and radioactive elements.Cesium is used in glassmaking and detection of radiation equipment.Potassium hydroxide is used in detergents and potassium bromide is a chemical that is used in photography. Potassium is used as a potassium hydroxide and it is used in fertilizers.Sodium is important for all living organisms. Sodium nitrate is an ingredient of gunpowder. Sodium is used as sodium nitrate and as table salt.It is also used to control certain mental disorders and glass. Lithium is used in the form of lithium carbonate and in batteries.Francium is discovered on 7th January 1939. Francium is an extremely radioactive element. Francium (Fr)įrancium is a short-lived radioactive element. Cesium (Cs)Ĭesium is a ductile, soft and silvery-white element of metal that is liquid at room temperature. Rubidium ignites spontaneously in the air. Rubidium is a soft and silvery-white element of metal. Potassium oxidizes rapidly in the air and tarnishes quickly. It is a highly reactive element of metal. Potassium is a silvery-white and soft element. Sodium is used in the production of industrially important compounds. Sodium is a light, soft and extremely malleable silvery-white element of metal. Lithium is used as a heat transfer medium in various alloys and optical forms of glass. Lithium is a silvery, soft and highly reactive element. The Alkali metals are as follows: Lithium (Li)
