A

A bond in which two atoms share two pairs of electrons

20
Q

Delocalised electrons

A

an electron that is able to move freely throughout a structure

21
Q

Electrostatic forces of attraction

A

Strong forces of attraction between oppositely charged particles

22
Q

Metallic bonding

A

A lattice of positive metal ions surrounded by delocalised outer electrons, held together by strong electrostatic forces of attraction

23
Q

Melting and boiling points of metallic substances

A

high

24
Q

Reason for metals high melting and boiling points

A

Strong electrostatic forces between positive metal ions and negative delocalised electrons

25
Q

Reason for metals being malleable

A

Layers of metal ions can slide over each other

26
Q

Reason alloys are harder than pure metals

A

Different sized atoms disrupt the layers of ions, preventing layers from sliding

35
Q

Reason graphite is soft

A

Weak forces between layers which can slide over each other.

36
Q

Reason graphite and graphene conduct electricity
