alkali metals
Alkali metals can be cut with a knife because they are soft and have low melting points. Iron cannot be cut easily with a knife because it is a strong and hard metal. The differences in properties between alkali metals and iron make alkali metals easier to cut with a knife.
Alkali metals and alkaline earth metals are both groups of elements on the periodic table, but they have distinct differences in their properties and reactivity. Alkali metals are located in Group 1 of the periodic table and are highly reactive, soft metals that easily lose their outermost electron to form positive ions. In contrast, alkaline earth metals are located in Group 2 and are less reactive than alkali metals, but still have a tendency to lose electrons to form positive ions. Alkaline earth metals are harder and have higher melting points compared to alkali metals. Overall, alkali metals are more reactive and have lower melting points than alkaline earth metals.
Alkali metals are highly reactive, soft metals that readily lose their outermost electron to form ions with a +1 charge. They are located in Group 1 of the periodic table. Alkaline earth metals are also reactive, but less so than alkali metals, and they lose two electrons to form ions with a +2 charge. They are located in Group 2 of the periodic table.
The elemental metal calcium is in Group(II) of the Periodic Table. Sometimes this Group is known as the ' Alkaline Earth Metals'. NOT 'Alkali metals', because alkali metals belong to Group (I).

No, in comparison to the rest of the metals, lithium (as an alkali metal) would be called a soft metal. All the alkali metals could be cut with a knife, but still retain properties of metals.
Alkali metals are from Group 1 of the Periodic table and have a single electron in their outer shell. Alkaline-Earth metals are in group 2 of the periodic table and have 2 electrons in their outer shell.
it is a common observation that metals of group 1 i.e., li,na,k,rb,cs and group 2,be,mg,ca,sr,ba are soft.similarly the metals of p-block elements in lower parts of groups are also soft but harder than alkali and alkaline earth which are s-block. the metals of d-and f-block elements are called hard metals.
Alkali metals can be cut with a knife because they are soft and have low melting points. Iron cannot be cut easily with a knife because it is a strong and hard metal. The differences in properties between alkali metals and iron make alkali metals easier to cut with a knife.

Transition state metals include a wide variety of metals; they include iron, gold, and Mercury which all have strikingly different properties (hard, soft, and liquid, for example). Nonetheless, a comparison can be made between the transition state metals and the alkali and alkaline earth metals; transition state metals are not as chemically active (some transition state metals are actually inert, such as platinum).
They are light, soft, silvery metals.
These are the alkali metals.
Alkali metals in Group I.
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
