Ionic compounds

Question 1

How are ionic bonds formed?

Answer 1

The transfer of electrons (loss or gain) to form charged particles - ions.

Question 2

What is oxidation?

Answer 2

When an atom loses electrons

Question 3

What is reduction?

Answer 3

When an atom gain electrons

Question 4

What makes an atom unreactive?

Answer 4

Atoms want a full outer shell - then they are unreactive

Question 5

What makes an atom reactive?

Answer 5

If they have a shell with just one electron or if they have a nearly full shell

Question 6

What is ionic bonding?

Answer 6

Strong electrostatic forces of attraction between oppositely charged ions - this gives them high melting and boiling points

Question 7

What are some common cations?

Answer 7

Li+, Na+, K+, Be2+, Mg2+, Ca2+

Question 8

What are some common anions?

Answer 8

O2-, S2-, F-, Cl-, Br-

Question 9

What affects melting and boiling points?

Answer 9

The charges on the ions in a lattice affect the strength of ionic bonding, this increases mtp and bpt

Question 10

What is an ionic crystal?

Answer 10

A giant three-dimensional lattice structure held together by the attraction between oppositely charged ions

Question 11

Describe the positions of ions in Sodium Chloride?

Answer 11

A giant lattice with a pattern of alternating Na+ and Cl- ions
