Explanation:
As alkali is a base and it produce OH- when disolved in water. So we can say that they are called "alkaline" earth metals because they form "alkaline" solutions, hydroxides, when they react with water . "Earth" was the alchemists term for the oxides of alkaline earth metals.

Im 4 and my sis is 13. SHE told me she was on her period but then I told her there was this thing called subject and predicate and how she isnt supposed to have a period at the end of her statement because it wouldnt make any sense... and ya, it didnt go well cause' she put on a tantrum.
But the weird thing is that Google said this "Tantrums are most common between the ages of one and four, then decrease when children start school." SO HOW COME I DIDN"T HABE A TANTRUM!! life makes no sense.
P.S: I even saw mom buying DiApERS for her! Like I stopped my diapers and got potty trained about 1 or 2 months ago and IM 4. SHE IS 13.
man she must have a hard time walking with those things in her short skinny pants.
