All alkali metals are found to be very soft and they have low melting and boiling points. Alkali metals have low binding energy in the metal crystal lattice as these atoms have only one valence electron. This results in the formation of metallic bonds which are not very strong. Also, alkali metals melting and boiling points decrease down the group.

Melting points of alkali metals?
Alkali metals have relatively low melting points compared to the other metals. Their exact melting points depend on the element itself. But it would be useful to note that their melting points decreases down group I.
What makes up alkali metals special?
Alkali metals are very reactive, not dense or hard metals, monovalent, with low electronegativities, with low melting and boiling points, react violently with water, form strong bases, etc.
All metals are hard and have high melting points?
No, the alkali metals are pretty soft and the metals cesium, gallium, and mercury have very low melting points.
Do group one metals have a high melting point?
No. Group 1 metals (commonly called the alkali metals) have low melting points.
What are denser harder have higher melting points and are slightly less active than alkali metals in the same period?
Alkali metals are very chemically reactive, are not dense or hard metals and have low melting points.
Which all metals have low melting and boiling points?
Mercury, all alkali metals (like Sodium) and alkaline-earth metals (like Calcium).
What is the Melting points of the alkali metals?
sodium

Silvery solids with low densities and low melting points found in group 1?
Silvery solids with low densities and low melting points are alkali metals. These are located in group one on the periodic table.
Explain why there is this pattern in melting points for francium?
The melting point of francium is not measured, only supposed by comparison with the melting points of the other alkali metals.
Which statement about alkali metals are correct?
Alkali metals belong to Group 1 of the periodic table. They are highly reactive and readily lose their outermost electron to form positive ions. Alkali metals have low melting and boiling points. They are soft and can be easily cut with a knife. Alkali metals include elements such as lithium, sodium, and potassium.
