Identify correct statements from the following.A) The compound with maximum ionic character is CsF.B) Ionic solids are crystalline.C) Ionic solids have high melting and boiling points.D) The second group element which forms predominantly covalent compounds is Beryllium.

A) The compound with maximum ionic character is CsF.Cs+- largest cation ; F-- smallest anionB) Ionic solids are crystalline.They have long range orderlinessC) Ionic solids have high melting and boiling points.Ionic bond is not only strong but ionic solids have 3D-structures.D) The second group element which forms predominantly covalent compounds is Beryllium.Polarization power of Be2+ is high due to small size.
