Electron Configuration For Alkaline Earth Metals
Alkaline earth metals are placed in 2nd group of the periodic table. They contain two electrons in the valence shell. As differentiating electron enters in s-orbital of the valence shell,they are called as s-block elements. The valence shell electronic cnfiguration of alkaline earth metals is found to be ns². The alkali metal electron configurations (group 1) always end with "s1" and the alkaline earth metals (group 2) always end with "s2". These 2 groups are know as "s block" elements. "P block" elementsare all those in groups 13-18 and always end with 1 or more "p" electrons. The general electron configuration of all alkaline earth metals is ns2. The alkaline earth metals are still too reactive to exist in nature as free elements, but they are less reactive than the alkali metals. They tend to be harder, stronger, and denser than the alkali metals, and they also form numerous compounds with nonmetals.
Alkali metals belong to the s-block elements occupying the leftmost side of the periodic table.Alkali metals readily lose electrons, making them count among the most reactive elements on earth. In this article, we will explain the electronic configurations, ionization enthalpy, hydration enthalpy and atomic, ionic radii and other physical and chemical properties of the group one alkali metals. Structurally, they (together with helium) have in common an outer s-orbital which is full; that is, this orbital contains its full complement of two electrons, which the alkaline earth metals readily lose to form cations with charge +2, and an oxidation state of +2. As we would expect, the first ionization energy of an alkaline earth metal, with an ns 2 valence electron configuration, is always significantly greater than that of the alkali metal immediately preceding it. The group 2 elements do exhibit some anomalies, however. All the alkaline earth metals have two electrons in their valence shell, so they lose two electrons to form cations with a 2+ charge. Most of the chemistry has been observed only for the first five members of the group; the chemistry of radium is not well established due to its radioactivity.

Since the alkaline earth metals have a completely full s-orbital in their respective valence shells, they tend to readily lose two electrons to form cations with a charge of +2. Thus, the most common oxidation state exhibited by the alkaline earth metals is +2. What is the general electron configuration of the alkaline earth metals? Answer Save. 2 Answers.

Elements that have similar chemical properties are grouped in columns called groups (or families).As well as being numbered, some of these groups have names—for example, alkali metals (the first column of elements), alkaline earth metals (the second column of elements), halogens (the next-to-last column of elements), and noble gases (the last column of elements). Alkaline earths have low electron affinities and low electronegativities. As with the alkali metals, the properties depend on the ease with which electrons are lost. The alkaline earths have two electrons in the outer shell. They have smaller atomic radii than the alkali metals.

The fourth electron fills the remaining space in the 2s orbital. An atom of boron (atomic number 5) contains five electrons. Alkaline Earth Metals Reactions, Uses, Properties. The general electron configuration of alkaline metals is [noble gas] ns 2 where n represents the valence shell. These metals forms +2 ions only. Alkaline earth metals are less reactive than alkali metals. Elements of Alkaline earth metals with electron configuration
The outermost orbitals are the s-orbitals and there are two electrons in each for the alkaline earth metals. The two valence electrons are lost to form ions, and therefore the charge will be +2. Be -- 1s2, 2s2. Mg -- 1s2, 2s2 2p6, 3s2. Ca -- 1s2, 2s2 2p6, 3s2 3p6, 4s2. Sr -- 1s2, 2s2 2p6, 3s2 3p6 3d10, 4s2 4p6, 5s2 As we would expect, the first ionization energy of an alkaline earth metal, with an ns2 valence electron configuration, is always significantly greater than that of the alkali metal immediately preceding it. The group 2 elements do exhibit some anomalies, however. Which family (group) of elements has a valence-level electron configuration of 𝑠1?. alkaline earth metals. alkali metals. halogens. noble gases
