Get the Anal Earthquake mug.Any element of the periodic table which is in group 2.
In order of proton number, Beryllium, Magnesium, Calcium, Strontium, Barium and Radium are all Alkaline Earth Metals.
They are characterized by all having 2 outer-shell electrons (two electrons in their valence shell), alas their placing in group 2 of the periodic table.
They are all silver coloured, soft metals which react readily to form ionic compounds.
The name 'Alkaline Earth Metals' is derived from the fact that the oxides formed by the elements in this group produce basic Alkaline solutions, and the melting points are such that the elements remain solid (Earths) in fires. Alkaline Earth refers to the oxides themselves.
x + 2H2O --> x(OH)2 + H2
2x + O2 --> 2xO
2xO + 2H2O --> 2x(OH)2
Where x is an Alkaline Earth Metal.
Both processes are relatively efficient unless you consider Hydrogen, which is produced in the first, to be a waste product. The second process only produces the hydroxide.

Both processes are relatively efficient unless you consider Hydrogen, which is produced in the first, to be a waste product. The second process only produces the hydroxide.
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
Mg + 2H2O --> Mg(OH)2 + H2
Magnesium + Water --> Magnesium Hydroxide + Hydrogen
2Mg + O2 --> 2MgO

Get the matthew thiessen and the earthquakes mug.A period of unease preceeding a large earthquake. This is not a scientific term, although heat and humidity have been said to preceed major earthquakes.
The term can also be applied to tension between friends, possibly preceeding a fight.
