Question
The most electropositive amongst the alkaline earth metals is :
Options
A.Be
B.Mg
C.Ca
D.Ba
Solution
Electropositive character is the measure of ease of formation of cation by losing electron. With increasing atomic size, the ionization energy decreases and, therefore, the ease of formation of cation by losing the electron increases resulting into more electropositive character of the metal. Down the group, metallic character increases due to decreases in ionisation energy and so electropositive character increase.
