Q

Describe what happens to the electrons during the formation of an ionic bond between sodium and chlorine

A

Sodium loses one electron to become 1+ and chlorine gains that one electron to become 1-

Q

State properties of giant ionic lattice and explain how ionic bonding causes each property

A

Conduct electricity - because the ions can move freely when in molten or aqueous form, rigid- because it has a high electrostatic force of attraction, high melting point- because of large amount of energy needed to break apart the bonds

Q

Why can’t giant ionic lattice is conduct electricity when solid but they can when liquid?

A

Because the electrons can’t flow through the structure as they are locked in place when solid

Q

Describe what happens to the electrons during the formation of a covalent bond between carbon and hydrogen in methane

A

Carbon can lose or gain four electrons to become +4 or -4. Hydrogen then gains to get a full outer shell

Q

Explain how fullerenes could be used to deliver drugs into the body

A

They are hollow and cylindrical, so they carry things and roll

17
Q

Which is larger, an atom or a nanoparticle

A

Atoms are bigger. Atoms- 0.1nm, nano- 1-100nm

18
Q

Describe the structure and formation of a polymer

A

Polymers are mixes of plastics in long chains called monomers

19
Q

Name the polymer made from several monomers of butane

A

Polybutane

20
Q

What is the difference between a Thermosetting polymer and a Thermosoftening polymer?

A

Thermosoftening has weaker intermolecular forces. Thermosetting has cross links

21
Q

Describe metallic bonding

A

the electrostatic attraction between positive metal ions and delocalised electrons

22
Q

List 3 properties of metals and explain how metallic bonding causes each property

A

Conducts heat- because of the free movement of electrons, conducts electricity- because of the free movement of electrons, malleable- allows metal atoms to slide over each other without breaking the bonds

23
Q

What is an alloy?

A

A metal made by combining two or more metallic elements

24
Q

Why are alloys harder than pure metals?

A

Pure metals are softer as it is in rows so can slip and side

25
Q

Name the three states of matter and explain how the strength of the forces between particles influence the temperature at which is substance changes state

A

Solid, liquid, gas
The temperature determines how much energy is needed to change the substances state

26
Q

What do the following state symbols mean?
A) s
B) l
C) g
D) aq

A

A) solid
B) liquid
C) gas
D) aqueous

27
Q

What is the name of the temperature at which
A) a solid turns into a liquid?
B) a liquid turns into a gas?

A

A) melting point
B) boiling point
