why do alkali metals have different boiling and melting points than typical metals?

The melting and boiling points of alkali metal halides are high due to their ionic nature. For a given alkali metal ion the melting and boiling points decrease in the order F > Cl > Br > I...

All alkali metals are soft and have low melting and boiling points. As alkali metals have only one valence electron per metal atom, the energy binding the atoms in the crystal lattice of the metal is low. Con..

Metals have high melting and boiling point - Tungsten has the highest melting point where as Hg has low boiling point. Na and K have low melting points..

,(except graphite and iodine which are lustrous nonmetals) Solids at room temperature(except mercury and gallium which are liquids) May be solids, liquids or gases at room temperature. Strong and tough and high tensile strength. (exceptions are zinc, mercury and gallium) Not strong. low tensile str..

Hydrogen differs from alkali metals in some way..

Alkali Metals - The six elements belonging to group 1 of the periodic table, namely lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs) and francium (Fr) are called alkali metals. They constitute alkali metals because they..

Elements of group I A of the periodic table constitute a family of very reactive metals called alkali metals. They are lithium, sodium, potassium, rubidium, cesium and francium. All of them have one electron in the valence shell. They are called alkali ..

When ammonia is passed over heated sodium or potassium, amides are formed and hydrogen is set free. Alkali metal dissolved in liquid ammonia gives a blue solutions, which upon standing slowly, liberate hydrogen. The blue color of such solutions is due to the presence of sol..

.e., its reaction is fast and more exothermic. This also implies that the reverse reaction becomes more difficult i.e., the more reactive a metal, the more difficult it is to extract from its ore. The metal is also more susceptible to corrosion with oxygen and water. The reactiv..

The melting and boiling points of group 14 elements are much higher as compared to those of group 13 elements. Explanation: It is because the atoms of group 14 can form four covalent bonds with each other and, therefore, there are strong binding forces between their at..
