Alkali metals are found in Group 1 of the Periodic Table.
Their factors include being soft enough to cut and have low melting points and densities too. They all react viciously with water, releasing hydrogen and forming hydroxides. They stain rapidly even in dry air. They are never found un-combined in nature. Decreasing down the periodic table (increasing atomic number) the alkali metals are: lithium,
sodium, potassium, rubidium, caesium and francium.
The alkali metals are the elements Lithium, Sodium, Potassium,
Rubidium, Caesium and Francium. They are grouped together
because they all behave similarly (except with different strengths) and together form Group 1 of the Periodic Table.
They are in fact very soft metals that can be cut with a knife. They do not occur naturally because they react readily with air and moisture and so need to be stored under oil.
One of the signature reactions of alkali metals is their reaction with water to form alkaline solutions, for example sodium reacts with water to form sodium
hydroxide.
The reaction of alkali metals with water is pretty vigorous and as we see in the video clip as we go down Group 1 of the Periodic Table, from Lithium to Caesium, things get more and more frightening.
Lithium is used to make
rechargeable batteries and
lightweight alloys. Some of its
compounds are used as mood
stabilising drugs.
Sodium (vapour) is used in bright yellow street lights. It is also used as a heat transfer agent in some types nuclear reactor. Sodium salts are
essential to life - ordinary table salt is sodium chloride.
Potassium salts are used as
fertilisers, such as potassium
chloride which used to be called chloride of potash. Potassium nitrate is one of the components of
gunpowder. Potassium salts are also essential to life.
Rubidium and Caesium have a
number of specialist uses such as the use of Caesium in atomic clocks that are very accurate and Rubidium, used in specialist glasses. Francium is an extremely rare metal mainly
because it readily undergoes
radioactive decay with a half life of less than 22
minutes.
Due to the lack and short half life, there are not many uses for francium other than scientific research.
Proven from my research I can tell that there are many benefits we can consider when using alkali metals for example: it helps people with
medicine issues, can contribute to batteries in a mobile and is a factor of glass for lenses or tubes inside TV's. Lithium is the main source and can be used for all sorts of
technology.
I hope the above information helps you

they are called alkali metals
The alkali metals exist in group one of the periodic table; as such, they are in the s-block. The electron configuration for each alkali metal ends in ns1. When represented in an Aufbau diagram, the outer shell electron has an "up" spin. Because of their single outer shell electron, alkali metals react well with halogens.

The Alkali Metals are: -lithium -sodium -potassium -rubidium -cesium -francium These metals are silvery solids with low densities and melting points.
Alkali metal forms Alkali while metals form bases.
Alkali Metals: the alkali metals are found in the first group of the periodic table, Alkali metals are very reactive metals and they are not freely in their nature, alkali metals have one electron in their outermost shell. therefore alkali metals are ready to loose that one electron for bonding with other elements, alkali metals are good conductor of electricity and heat. they are soft in nature than other metals.The Alkali Metals are:lithium, sodium, potassium, rubidium cesium, francium

The alkali earth metals act in a similar but slightly less reactive way to alkali metals

its definitley not acid Some metals are called alkali metals or alkaline earth metals because they often form alkaline compounds; but metals are not alkali or acids.
The elements in Group 1 of the periodic table are called the alkali metals. The elements that make up this group are Lithium, Sodium, Potassium, Rubidium, cesium, and Francium. Hydrogen is not in this group even though it may look like it. The alkali metals are highly reactive metals that do not occur freely in nature. These metals have only one electron in their outer shell making them ready to lose that one electron in ionic bonding with other elements. Some other cool facts are: --Like other metals, alkali metals are malleable, ductile, and are good conductors of heat and electricity --The alkali metals are softer than most other metals. --Alkali metals can explode if they are exposed to water.

Alkali metals are the most reactive metals.
