Write a generic Lewis structure for the alkaline earth metals. Do the alkaline earth metals tend to gain or lose electrons in chemical reactions? How many?
The alkaline earth metals beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra)) are a group of chemical elements in the s-block of the periodic table.
Lewis structure of Mg :-
12Mg [Ne] 3s2 It has 2 electrons in its valence shell. Hence the Lewis structure is,
Lewis structure of Be
4Be 1s2 2s2 It has 2 electrons in its valence shell. Hence the Lewis structure is,
All the elements present in group 2, have two electrons in the valence shell. So the Lewis structure is as follows
Ca : Sr: Ba: Ra:
The alkaline earth metals tend to lose electrons because they have valency +2 and by losing two electrons all the metals will attain the nearest inert gas configuration (octet rule) and become stable.
