alkaline earths

In keeping with the naming of the other alkaline earths, he changed the name to strontium.

Beryllium difluoride is very soluble in water, unlike the other alkaline earths.

Later, he suggested that the alkaline earths might be metal oxides, but admitted that this was mere conjecture.

Beryllium through radium are the alkaline earths, as they also make strong bases when contacted with water, but the resulting materials aren't particularly soluble.

"Earths" later turned out to be chemical compounds, albeit difficult to concentrate, such as rare earths and alkaline earths.

The soil of one district consists of sandstone; certain trees find in it a quantity of alkaline earths sufficient for their own sustenance.

Dry bromine reacts vigorously with aluminium, titanium, mercury as well as alkaline earths and alkali metals.

Clay minerals are hydrous aluminium phyllosilicates, sometimes with variable amounts of iron, magnesium, alkali metals, alkaline earths, and other cations.

Magnesium oxide and calcium oxide were found to have an alkaline reaction, and hence were called the alkaline earths.

The alkaline earth metals are named after their oxides, the alkaline earths, whose old-fashioned names were beryllia, magnesia, lime, strontia and baryta.

On the other hand, the fluorides of the alkaline earths are generally very insoluble (despite being quite ionic), while the alkali earth chlorides are fairly soluble.

In anaerobic, and particularly geothermal conditions, the divalent form is sufficiently stable that it tends to be incorporated into minerals of calcium and the other alkaline earths.

Calc-alkaline rocks are rich in alkaline earths (magnesia and calcium oxide) and alkali metals and make up a major part of the crust of the continents.

Salt-like carbides are composed of highly electropositive elements such as the alkali metals, alkaline earths, and group 3 metals including scandium, yttrium and lanthanum.

So, the trend in this group is unlike the trend in group 2, the alkaline earths, where metallic radius increases smoothly from top to bottom of the group.

In general, beryllium has a tendency to bond covalently, much more so than the other alkaline earths and its fluoride is partially covalent (although still more ionic than its other halides).

Magnesium hydroxide Mg(OH) is a weak base but calcium hydroxide is a strong base as are the hydroxides of the heavier alkaline earths, strontium hydroxide and barium hydroxide.

Bands for FeH (and other hydrides of transition metals and alkaline earths) show up prominently in the emission spectra for M dwarfs and L dwarfs, the hottest kind of brown dwarf.

Soap is produced by combining fats or oils with alkalies or alkaline earths, usually by boiling, and consists of salts of sodium, potassium, etc., with the fatty acids (oleic, stearic, palmitic, etc.).
