Alkaline Earth

I have found that this method gives very good results even with quite small amounts of substance (0.1 to 0.5 g), provided a very fast balance is used to avoid the absorption of water by the alkaline-earth salt during the weighings. ❋ Unknown (1966)

Radium is the higher homologue of barium in the family of alkaline-earth metals; it has been entered in Mendeleev's table in the corresponding column, on the row containing uranium and thorium. ❋ Unknown (1966)

What properties have the metals of the magnesium family in common with the alkali metals; with the alkaline-earth metals? ❋ William McPherson (N/A)

Like the alkaline-earth metals, their carbonates and phosphates are insoluble in water. ❋ William McPherson (N/A)

_ The members of this group are divalent in nearly all their compounds, so that the formulas of their salts resemble those of the alkaline-earth metals. ❋ William McPherson (N/A)

Unlike both the alkali and alkaline-earth metals, their hydroxides are nearly insoluble in water. ❋ William McPherson (N/A)

They are called the alkaline-earth metals because their properties are between those of the alkali metals and the earth metals. ❋ William McPherson (N/A)

~ The alkaline-earth family consists of the very abundant element calcium and the much rarer elements strontium and barium. ❋ William McPherson (N/A)

What properties have the alkaline-earth metals in common with the alkali metals? ❋ William McPherson (N/A)

Zeolites are a group of micro-porous, crystalline minerals with well-defined structures of the alkaline or alkaline-earth metals. ❋ Amp;34; (2010)

[Magnesium] is an [Alkaline] Earth Metal - it, and its oxide, react with water to form a basic [alkaline] solution. Mg + 2H2O --> Mg(OH)2 + H2 Magnesium + Water --> Magnesium [Hydroxide] + Hydrogen 2Mg + O2 --> 2MgO Magnesium + Oxygen --> Magnesium Oxide 2MgO + 2H2O --> 2Mg(OH)2 Magnesium Oxide + Water --> Magnesium Hydroxide The electron configuration of Magnesium is 2,8,2 - two electrons in its outer/valence shell ❋ Ceeell (2009)
