3. Chemical Bonding & Structure

Question 1

Ionic Bond

Definition

Answer 1

Ionic bonds are strong electrostatic forces of attraction between oppositely-charged ions.

Question 2

Structure of Ionic Compounds

Answer 2

Giant ionic structure

Consists of a continuously repeating 3-dimensional lattice of positive and negative ions.
Ions are closely packed, arranged in an orderly manner, and held in fixed positions by strong electrostatic forces of attraction between oppositely-charge ions.

Question 3

Melting Point of Ionic Compounds

Answer 3

Ionic compounds generally have high melting points and exist as solids at r.t.p.

Ionic compounds have a giant ionic structure.
Large amount of energy is required to overcome the strong electrostatic forces of attraction between oppositely-charged ions.

Question 4

Electrical Conductivity of Ionic Compounds
