Ionic Bonding

Question 1

how to form cations

Answer 1

metals lose electrons

Question 2

how to form anions

Answer 2

non-metals gain electrons

Question 3

upon losing or gaining electrons, the ions formed obtain what

Answer 3

obtain the electronic configuration of a noble gas/stable electronic configuration

Question 4

draw full electronic arrangement of ionic bonding between Na and O

Answer 4

Question 5

ionic compounds structure (3 points)

Answer 5

-giant ionic lattice structure
-where oppositely charged ions are held together
-by strong electrostatic forces of attraction

Question 6

explain why ionic compounds have high melting point (2 points)

Answer 6

-ionic compounds have giant ionic lattice structure
-large amount of energy is required to overcome the strong electrostatic forces of attraction between oppositely charged ions

Question 7

explain why ionic compounds cannot conduct electricity in solid state (2 points)

Answer 7

-ions are held in fixed positions and are immobile,
-hence there is no mobile ions to conduct electricity

Question 8

explain why ionic compounds can conduct electricity in molten and aqueous states

Answer 8

there is presence of mobile ions to conduct electricity
