Alkaline Earth Metals
ALKALINE EARTH METALS what are alkaline earth metals?
Alkaline earth metals are elements that are in the second group of the periodic table. the elements have two electrons on the outermost shell. the elements include Beryllium, magnesseum, calcium,strontium, barium and Radium.The alkaline earth metals are all silver­colored and soft, and have relatively low

densities, melting points, and boiling points. In chemical terms, all of the alkaline metals react with the halogens to form the alkaline earth metal halides
Why are the called alkaline earth metals

The alkaline earth metals are named after their oxides, the alkaline earths, whose old­fashioned names were beryllia, magnesia, lime, strontia, and baryta. These oxides are basic (alkaline) when combined with water. "Earth" is an old term applied by early chemists to nonmetallic substances that are insoluble in water and resistant to heating—properties shared by these oxides. Physical Properties of Alkaline Earth metals 1.

They normally conduct electricity well.

2.

They are extremely reactive and radium is radioactive and harmful to life.

Physical properties 3.

Alkaline earth metals have a higher melting point than other metals in different groups.

4.

Alkaline earth metals are relativly dense.

5.

And finally, alkaline earth metals are relatively hard.

Chemical Properties:
1.

All of the alkaline earth metals form an oxide (rust) on their surface at room temperature (except for
Beryllium).

2.

All of the alkaline earth metals (except Beryllium) reduce water and dilute acids to hydrogen.

3.

Magnesium can reduce, and burn in, carbon dioxide. https://www.youtube.com/watch?v=_xCbal2YyaE https://www.youtube.com/watch?v=FofPjj7v414

    3. Alkali metals (group 1) have 1 electron in their outermost energy level, the s sublevel, and they want to lose that electron, that is why alkali metals react vigorously with nonmetals, especially halogens, because halogens need 1 electron to be stable. All alkali metals react with water to produce hydrogen gas and substances called alkalis. Alkaline earth metals (group 2) are less reactive than alkali metals because alkaline earth metals have 2 electrons in the s sublevel. Because the main energy level is filled, they are less likely to lose or gain an electron.…

    Bases are substances that are in aqueous solution, are slippery to the touch, taste bitter, change the color of indicators Examples turn red litmus paper blue and react with acids to form salts, promote certain chemical reactions. General properties of a base are Concentrated or strong bases and are caustic on organic matter and react violently with acidic substances. Also bases can are bitter in taste. And the pH of a basic solution at standard conditions is greater than seven. Strong bases are a basic chemical compound that can remove a proton (H+) from (or deprotonate) a molecule of a very weak acid in an acid-base reaction. Example of a strong base is lithium hydroxide, calcium hydroxide and strontium hydroxide just name a few but there…

    Aluminum is a tin-white metal which melts at 640°C and boils at 2,327-2,450°C (N/A, 2012). It is very light and has a density of 2.68g. It is both ductile and malleable, making it stiff and strong, and with frequent annealing it can be rolled into thin foil (N/A, 1996-2012). It is a good conductor of heat and electricity, and it is a solid in its standard state. One of Aluminums chemical properties is that in moist air, it combines slowly with oxygen to form aluminum oxide. The aluminum oxide forms a very thin, whitish coating on the aluminum metal (N/A, n.d.). This element is also a fairly active metal. It reacts with many hot acids and with alkalis. Aluminum also reacts quickly with hot water, and in powdered form, it catches fire quickly when exposed to a flame (N/A, 1996-2012).…

    Alkali metals contain a single electron in their outer shell rendering them highly reactive. This allows them to be ready to donate this single electron to form molecules with substances like water. Halogens are also extremely reactive containing seven electrons in their outer shell. Similar to alkali metals, halogens need only one electron in their outer shell to become stable. The reactivity of an element increases the when the number of outer shell electrons is closer to one or seven. Elements that contain eight electrons in their outer shell exhibit little or no reactivity. Alkali metals are the elements found in group one of the periodic table. Mixing these…

    The definition of reactivity as pertained to chemistry states, “The relative capacity of an atom, molecule, or radical to undergo a chemical reaction with another atom, molecule, or compound” (Reactivity, 2014). The reactivity of some elements or gases is greater than that of others. When Dmitri Mendeleev created the periodic table he arranged the elements based on their relative atomic mass. Alkali metals are very reactive when mixed with other elements and are placed in Group 1A of the periodic table. There are also extremely reactive nonmetal elements called halogens and are known to be in group 7A in the periodic table. Both the alkali metals and the halogens (nonmetals) on considered to be main group elements. When the number of outer shell electrons is closer to one or seven the higher the elements reactivity. Alkali metals contain a single electron in their outer shell which makes them highly reactive and halogens contain only seven electrons in their outer shell. Noble gases, such as helium, are not reactive because they are chemically stable and will not combine with other elements.…

    Arsenic, a silver-gray metal-like element, can be found throughout the earth’s crust. It is assigned atomic number 33 in the periodic table, and has a relative atomic mass of 74.92.(1) Being found throughout the earth crust, it is the twentieth most abundant element and is found in our air, water, and soil. Arsenic is usually combined with other elements, forming compounds with oxygen, chlorine, and sulfur; and it is in both organic and inorganic forms. Organic arsenic is combined with carbon and hydrogen, where inorganic binds with elements such as oxygen, chlorine and sulfur. Common inorganic compounds of arsenic are trivalent arsenic and pentavalent arsenic; and two reocurring organic compounds are monomethyl arsonic acid and roxarsone.…
