The softness of alkali metals has to do with metallic bonding in terms of bonding and anti bonding orbitals. In molecular orbitals, there are the s, p, d orbitals with corresponding anti-bonding orbitals. For alkali metals, the s orbital is only partially filled. This means that the bonds between each atom are weak because only a cloud of s-orbital electrons are holding them together. As we move right across the Periodic Table the strength of metals reach a maximum at about group 7-8. This is because at this point anti-bonding and bonding orbitals are both partially filled and this maximizes the amount of unpaired electrons that participate in the electron cloud that holds metallic bonds together. As we proceed further right (toward Au) the bonds become weaker because the bonding and anti-bonding orbitals begin to fill and pair up. This means these electrons do not participate in the electron cloud of metallic bonding. Thus a weaker bond (softer metal) is formed.
Yes, alkali metals are malleable because they have metallic properties which allow them to be hammered or pressed into thin sheets without breaking. However, they are softer and more reactive compared to other metals, so they require careful handling.
By forming their oxides, the alkali metals tarnish very quickly with respect to many other metals.
Group 1A elements are active metals. They are so active that they are never found free in nature. They are usually stored in oil. They form compounds with oxygen that dissolve in water to give solutions that are alkaline or caustic. They are called alkali metals, or simply the alkalis.
non-metals .... alkali metals....transition metals....alkali earth metals....rare earth metals....other metals....halogens....inert elements
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
Potassium, sodium, and lithium are softer and more reactive than other metals. They are typically stored in oil or kerosene to prevent them from reacting with moisture in the air.

They don't
Alkali metals are very reactive metals.
yes, the metals are next to each other
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.
By forming their oxides, the alkali metals tarnish very quickly with respect to many other metals.
