Question

Q- Of the metals Be, Mg, Ca and Sr of group 2 in the
periodic table, the least ionic chloride will be formed
by
(a) Be
(b) Ca
(c) Mg
(d) Sr​

Answer 1

Answer:

Be

Explanation:

Be will have a smaller size and will have least electropositivity. The less electropositivity , the lesser cationic character and hence the least ionic chloride is with Be .

Moreover , the greater electronegativity difference the greater the ionic property. Be and Cl have less E.N difference as compared to Sr and Cl.
