principles of chemisty - ionic bonding

Question 1

charges for ions in groups 1,2,3,5,6,7

Answer 1

+1, +2, +3, -3, -2, -1

Question 2

charges for Ag+, Cu2+, Fe2+, Fe3+, Pb2+, Zn2+

Answer 2

+1, +2, +2, +3, +2, +2

Question 3

charges for hydrogen (H+), hydroxide (OH–), ammonium (NH4+), carbonate (CO32–), nitrate (NO3-), sulphate (SO42–)

Answer 3

+1, -1, +1, -2, -1, -2

Question 4

what is ionic bonding in terms of electrostatic attraction?

Answer 4

the electrostatic force of attraction between a positively charged metal ion and a negatively charged non-metal ion

Question 5

why do compounds with giant ionic lattices have high melting and boiling points

Answer 5

Because of the strong electrostatic forces between them, it takes a great deal of energy to separate the positive and negative ions in a crystal lattice

Question 6

do solid ionic compounds conduct electricity?

Answer 6

no, but they do when they are molten or aqueous
