The alkaline earth metals are all of the elements in the second column (column 2A) of the periodic table. This group includes beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba) and radium (Ra). Alkaline earth metals have only two electrons in their outermost electron layer.
Alkaline earth metals get the name 'alkaline' because of the basic nature of the compounds they form when bonded with oxygen.
properties:-
Alkaline earth metals in their pure forms are generally shiny and silvery. They rarely occur in their pure form, however, because they are very reactive. Alkaline earth metals have two electrons in their outermost electron layer, which take relatively little energy to remove. The energy it takes to remove an electron from an element is called the ionization energy. Alkaline earth metals have relatively low ionization energies for their first two electrons; because of this, alkaline earth metals exist with a 2+ charge most of the time. It is most common to find them in ionic compounds or as ions.

Alkali earth metal-
1. In this group the elements present are beryllium, magnesium, calcium, strontium, barium and radium.
2. They are divalent elements.
3.on moving down the group their size or radius increases as the addition of an extra shell.
4. Their ionisation enthalpy is low.
5. Their hydration enthalpy is also low due to the increase in size
6. Their oxidation state is +2.
