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.

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.


What is the melting and boiling point of metals?

Which metal needs to be specified. Look in a Chemistry book or reference book. All metals have their own melting and boiling points - that's one of the ways we identify which metal the item is made of.


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.


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.


What are denser harder have higher melting points and are slightly less active than alkali metals in the same period?

These are characteristics of alkaline earth metals, such as calcium and magnesium. They have tightly packed metallic lattices, making them denser and harder than alkali metals. Their higher melting points and lower reactivity compared to alkali metals can be attributed to their lower atomic size and increased nuclear charge.

Why melting and boiling point of alkali metals are lower as compared to alkaline earth metals?

Alkali metals have weaker metallic bonding due to their larger atomic size and lower charge density compared to alkaline earth metals. This results in lower melting and boiling points for alkali metals because less energy is required to overcome the forces holding the metal atoms together. Additionally, alkali metals have only one valence electron, making it easier for them to lose this electron and transition into a liquid or gaseous state.

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.


What is the trend in melting point and boiling points of the elemets in group 1 and 7?

In Group 1 (alkali metals), the melting and boiling points decrease as you move down the group due to the increase in atomic size and metallic bonding. In Group 7 (halogens), the melting and boiling points increase as you move down the group due to the increase in atomic size and London dispersion forces.
