Alkaline Earth Metal

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.

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

Absolutely amazing band consisting of legends Matt Skiba, Dan Andriano and Derek Grant. No other artist/band out there can even slightly compare to their greatness through lyrics which are so emotional and poetic, it makes me think if there is any point in other people trying to be better than them.

Their latest record "Crimson" maintains the same sadistic topics that they cover best. My all time favourite band, undoubtedly.

Listen to Radio, Sadie, Prevent This Tragedy, Take Lots With Alcohol and This Could Be Love....then you'll understand.

Cool Band. Pure Poetry . There sorta the dark side of a mix between emo and indie. all agree with each other please as you should be rippin the piss out of folk who listen to music u disagree with. my personal hatred towards hip-hop , metal and dance.

Goth-trended Person : "rarrr death metal rules dude!"
Alk3 Fan : "actually, i rule. i just won 10 quid in the lottery. oh yeh and that shit aint real music. scientific evidence proves it distorts ur brain patterns till u go retarded....."

Alkaline Trio

A rock band made up of Matt Skiba on guitar, Dan Andriano on bass, and Mike Felumlee on drums. They have quite a few albums such as "I Lied My Face Off", "From Here to Infirmary", and "Good Mourning". The name came around because they wanted it to be "________ trio" and so they started going through the dictionary and found Alkaline.

I saw Alkaline Trio at Warped Tour and they rocked that shit like a vandal.
