Health and reactivity of the alkaline earth metals are quite high if compared not with the alkali metals but with any other elements of the fourth and fifth groups. This process, called oxidation, is a result of these metals’ natural tendency to donate their valence electrons to become ions ...
Why are the Alkaline Earth Metals so Reactive The energy required to make an atom give up the electrons in its outermost shell (valence electrons) is the ionization energy for the element. The lower the ionization energy, the more reactive an element is. Since all the alkaline metals have on...
- Alkali metals have the electron configuration ending in ns¹. 3. Metallic Bonding: - The melting point of metals is largely influenced by the strength of metallic bonds, which depend on the number of delocalized electrons. - Alkaline earth metals have two valence electrons, which can contrib...
valence electronsThe problem associated with the structure of alkaline earth metals in the liquid state is solved by using the one-component plasma approximation. In this approximation, any metal in the liquid state is treated as a system of coulombically interacting, positively charged, identical ...
It explains the paradoxical situation that only 16 valence electrons of the 18-electron species M(N2)8 (M=Ca, Sr, Ba) are used to fill the valence shell of the metals. The HOMO (highest occupied molecular orbital) is degenerate; the occupation by two electrons with the same spin gives ...

Which group contains the alkali metals? a. 1A b. 2A c. 3A d. 8A What is between metals and nonmetals on the periodic table? How many valence electrons do alkaline earth metals have? Explore our homework questions and answers library ...
Alkaline Earth Metals have their s-subshell filled with 2 valence electrons. Understand properties, electronic configuration, analogous behaviour, reactivity, ionization energy of group 2 alkaline earth metals.
One suggested explanation for the bending in these compounds is that the filled “semi-core” (n− 1)pand the valence (n− 1)dorbitalsof the heavier alkaline-earth metals are involved in bonding (for calcium, this means the 3pand 3dorbitals; for strontium, the 4pand 4d; for barium,...
We have also studied the substitution patterns of metals with different valences, which has demonstrated the ability of some germanides to accommodate substitutions and wider valence electron count while maintaining their global structural integrity. Good examples of the latter approach, and its effects...
