Ionic Structure, Bonding and Properties

Question 1

what is the structure of an ionic compound?

Answer 1

the ions are arranged in a giant ionic lattice

Question 2

what is the definition of ionic bonding?

Answer 2

ionic bonding is the electrostatic attraction between oppositely charged ions

Question 3

what is a feature of ionic bonding?

Answer 3

• it is always a very strong attraction

Question 4

what is a feature of ionic bonding?

Answer 4

• it is always a very strong attraction

Question 5

why do ionic compounds have high melting points?

Answer 5

• the ionic bonds are very strong
• in a giant ionic lattice there are lots of ionic bonds
• breaking all the ionic bonds requires a large amount of energy

Question 6

why do some ionic compounds have higher melting points?

Answer 6

• their ions have higher charges
• this makes the attraction between the ions even stronger and harder to break

Question 7

what does electrical conductivity require in ions?

Answer 7

charged particles that can move freely
