Ionic Structure + Ionic Bonding

Question 1

Elements?

Answer 1

Substance that cannot be broken into anything

Question 2

Compound?

Answer 2

Two or more different elements chemically bonded together (they do this to achieve a full outer shell)

Question 3

Mixture?

Answer 3

Two or more (alloy) substances NOT chemically joined together

Question 4

Alloy?

Answer 4

Mixture of a metal with other metals/elements

Question 5

Chemical changes?

Answer 5

These are irreversible changes - normally produce delta T, a gas, a colour change, a smell, a sound, producing light energy… —> produce a new material

Question 6

What is an ionic bond?

Answer 6

They are formed between metals and non-metals

Question 7

Do metals gain or lose electrons and what do they form?

Answer 7

Lose electrons to form positively charged ions (cations)

Question 8

Do non-metals lose or gain electrons and what do they form?

Answer 8

Gain electrons to form negatively charged ions (anions)

Question 9

What is the ionic bone? (Electrostatic force) GCSE

Answer 9

The ionic bond is the electrostatic force of attraction between oppositely charged ions

Question 10

What do the ions form and what is the result?

Answer 10

They form a giant lattice, the resulting compound has no overall charge

Question 11

What is the difference between a lattice and an ionic lattice?

Answer 11

Lattice - regular patterns of atoms
Ionic lattice - regular pattern of alternating positive and negative ions
