chem bonding: ionic bonds

Question 1

what are ionic bonds?

Answer 1

electrostatic forces of attraction between oppositely charged ions

Question 2

how are ionic bonds formed?

Answer 2

as a result of electron transfer from the valance shell of one atom to another

Question 3

giant ionic lattice structure of ionic compounds?

Answer 3

there is maximum attraction between oppositely charged ions and minimum repulsion between similarly charged ions

Question 4

why do ionic compounds have high mp and bp?

Answer 4

large amount of energy is required to break the strong ionic bonds

Question 5

how does ionic charge affect strength of ionic bonds?

Answer 5

as ionic charge increases, attraction between oppositely charged ions increase

Question 6

how does ionic size affect ionic bonds?

Answer 6

as ionic size decreases, attraction between oppositely charged ions increase

Question 7

why are ionic compounds hard and brittle?

Answer 7

because the ionic bonds are strong and non-directional

Question 8

solubility of ionic compounds

Answer 8

soluble in polar solvents, insoluble in organic solvents

Question 9

can ionic compounds conduct electricity?

Answer 9

yes, in molten and aqueous solutions
