The meaning of ALKALINE EARTH METAL is any of the divalent strongly basic metals of group II of the periodic table comprising beryllium, magnesium, calcium, strontium, barium, and radium —called also alkaline earth.
Why are the Alkaline Earth Metals so Reactive The energy required to make an atom give up the electrons in its outermost shell (valence electrons) is the ionization energy for the element. The lower the ionization energy, the more reactive an element is. Since all the alkaline metals have on...

Properties of the Alkaline Earth Metals The alkaline earths possess many of the characteristic properties ofmetals. Alkaline earths have low electron affinities and lowelectronegativities. As with thealkali metals, the properties depend on the ease with which electrons are lost. The alkaline earths ha...

All the alkaline earth metals have larger size and therefore, the nuclear force of attraction between the last two electrons and protons is less in magnitude. Therefore, they are loosely held and on application of a little amount of heat or energy, these two electrons...
