Question

Alkaline earth metals always form dipositive ions due to
(A) IE

(A) IE2- IE1, > 10 eV
(B) IE2 - IE1, = 17 eV
(C) IE2 - IE1, < 10 eV
(D) None of these
​

Answer 1

Answer:

c

Explanation:

in alkaline earth metal the outer electronic configuration is ns^2

therefore its looses 2 electrons to become stable . since removing 2 electrons make it stable the second ionisation enthalpy of alkali earth metal is less than its first ionisation enthalpy therefore making their differences less than 10ev
