Alkaline Earth Metals Overview

The document discusses the alkaline earth metals, which make up group 2 of the periodic table. The 6 elements in this group are beryllium, magnesium, calcium, strontium, barium, and radium. They have similar chemical properties, including having 2 valence electrons and being very reactive. Each element has important uses - for example, calcium makes up bones and strontium produces the red color in fireworks. The alkaline earth metals have metallic bonds that make them hard but softer than most other metal groups. Their reactivity with water ranges from less reactive (beryllium) to vigorously burning (magnesium). Calcium was discovered in 1808 through electrolysis.

Group two of the periodic table consists of the elements known as the ”Alkaline Earth Metals.”.

In their Family name, it merely states they are metals.

For each of the six elements in group two, their names, along with their chemical symbols

going from top to bottom of the table, are known as; Beryllium: Be, Magnesium: Mg, Calcium:

Ca, Strontium: Sr, Barium: Ba, Radium: Ra. At room temperature, these elements are solids such

as Calcium. All of these have two valence electrons; these are the electrons commonly used in

chemical reactions; this makes these elements very reactive.

Each element has a point to it, or also known as a use. “Boing” goes a simple spring thanks

to Beryllium, it is also used in Non-sparking tools, used for high-speed aircraft, and even

Missiles. Like living, good because without Magnesium, the 300 enzyme reactions wouldn’t do

what they need to do. Calcium makes up Bones from fingernails to our teeth. Fireworks anytime

can be enjoyable, but one of the most critical colors in our flag for the Fourth of July is red.

Strontium produces that lovely red color in the explosives. That weird thing in your body to let

you eat food and not let that stomach acid leak out is that coating in it and even in your throat.

Barium is that exact coding or makes up that coding. Cancer is a not so great thing, but with

Radium, it can be treated, but most result in hair loss.

All of each element or group of items have one or more than plenty of physical and chemical

properties. Of the many, one of the physical features of the Alkaline Earth Metals is their

hardness. Compared to group one, these elements in group two are among the strongest, due to
the durable metallic bonds in the nucleus. These metals are also a lot softer than most metals than

in other groups.

For the reactions of water when added to an element with group two, most of the aspects

of group two are more reactive besides Beryllium. The reason for Beryllium being less

responsive to water is the active oxide layer on the surface of it. When the addition of

magnesium is added to water, it's minor but burns vigorously with water vapor to produce oxide

and a gas.

The element Calcium was discovered in 1808 and named after a Latin name, also known as

calx, meaning lime. When Sir Humphry Davy electrolyzed a mixture of lime and mercuric acid,

he came up with this Calcium-like element.
