Nov 06, 2014· The alkaline earth elements. The alkaline earth elements are the metallic elements found in the second group of sblock after group ( 1 A ) . They are located on the left side of the modern periodic table . The alkaline earth metals are all shiny, silverwhite and they are good conductors of the heat and the electricity .
metals and ns1 for alkali metals. But for the alkaline earth metals, the nucleus also contains an additional positive charge. Also, the elements of Group 2 (alkaline earths) have much higher melting points and boiling points compared to those of Group 1 (alkali metals). The alkalis are softer and more lightweight than the alkaline earth metals ...
Jul 04, 2015· Best Answer: The alkaline earth metals are those found in group 2 on the periodic table and include Ca, Sr and Ba. They form basic oxides with the general formula MO, and M (OH)2 in solution. That is why there is the word "alkaline" in the name. The reverse is true. They form MX2 as metal halides because their oxidation state is +2.

Alkaline earth metals share many traits with metals. Uniquely, they have two electrons on the outer shell. Although alkaline earths share many traits with the alkali metals, alkaline earths have a smaller atomic radii because the two valeance electons are not as tightly bonded with the nucleus as they are in alkali metals.

Alkalineearth metal oxides, especially for magnesium oxide [2, 3], were effective catalysts for the MPV reaction under mild conditions. In this study, one nitridation process was for the first time introduced to adjust the basic strength of BaOMCM41. The asnitrided samples were systemically characterized and testified for the MPV reaction.
