Topic 2 metallic bonding and forces Flashcards
1
Q
metallic bonding
A
electrostatic attraction between positive metal ions and negative delocalised electrons
2
Q
Trend of higher melting point
A
The more electrons an atom can donate to the delocalised system, the higher the melting point
3
Q
Are metals good thermal conductors
A
Yes as the delocalised electrons can transfer kinetic energy
4
Q
Are metals insoluble
A
Yes as metallic bond is too strong to break
5
Q
Are metals good electrical conductors
A
Yes as delocalised electrons are mobile and can carry a current
6
Q
Metals have high melting points due to…
A
Strong electrostatic attractions.
7
Q
Metals and malleable and ductile as…
A
Layers can slide and still retain an attraction between ions and delocalised electrons
