Choose the correct order of increase in electropositivity of alkali earth metals in the options given below

  • a)
    Be2+<Mg2+<Ca2+<Sr2+<Ba2+

  • b)
    Sr2+ > Ba2+ < Be2+ < Mg2+ < Sr2+

  • c)
    Ca2+ > Sr2+ > Ba2+ < Be2+ < Mg2+

  • d)
    Mg2+ > Ca2+ > Sr2+> Ba2+ < Be2+

Correct answer is option 'A'. Can you explain this answer?

Answers

Correct Answer : a
Explanation : Atomic no. of Be, Mg, Ca, Sr, Ba are 4, 12,20,38,56 respectively.
On moving down the group, the effective nuclear charge on the outermost electrons decreases. Hence Ba can readily lose electrons and will be the most electropositive element among the alkaline earth metals.
