Why are the melting and boiling points of alkali metals higher than alkaline earth metals?

ANSWER

Because of smaller size and strong metallic bonding in close-packed structure, the melting and boiling points of the alkaline earth metals are higher than alkali metals. Among the alkaline earth metals except for magnesium, the melting and boiling points decrease regularly from beryllium to barium.

Why do alkaline Earth metals have a higher density ?

Group II metals have highter melting/boiling points because they have stronger metallic bonds than Group I (alkali) metals Melting/boiling points are a measure of the streng th of intermolecular bonds.

Why do Group() metals have higher melting point than ? Generally (but not always), the melting and boiling points fall steadily when passing from Group 2 to Group 1. This is because the ionic radii increase down the group increasing charge …

which are more reactive, alkali or alkaline earth metal? English is used when calling us. (703) 369-2100 or (703) 491-2222. Toggle navigation

Why does the melting point get lower going down the Alkali ? Why does the melting point get lower going down the Alkali Metal Group with increase in atomic number? Ok, you're looking for a generalization of what happens to the melting point as you go down a column in the periodic table. Think of the metal atoms as cations $\ce{M^+}$ and anions $\ce{M^-}$ packed into a crystal like NaCl.

Why alkali metals have low melting and boiling points ?

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. Are

why are group 2 elements called alkaline earth metals? Although many characteristics are common throughout the group, the heavier metals such as Ca, Sr, Ba, and Ra are almost as reactive as the Group 1 Alkali Metals. The alkaline earth metals are very reactive, although less so than the alkali metals. Alkaline-earth metal, any of the six chemical elements that comprise Group 2 of the periodic table.
