C2 - Transition Metals + Metallic Bonding Flashcards
1
Q
Describe metals in terms of its structure…
A
LAYERS of positive metal ions are held together in a lattice structure by DELOCALISED electrons
2
Q
Name four properties of metals…
A
They are:
- Malleable (bendy)
- Ductile (stretchy)
- High melting points
- High boiling points
3
Q
When a strong force is applied to a metal what occurs? Why is this?
A
When a strong force is applied to a transition metal, because of the strong force between the metal ions and the delocalised electrons, the metal spreads rather than breaking due to the presence of layers.
4
Q
Why can transition metals conduct electricity?
A
Because many delocalised electrons are present in order to induce a current.
5
Q
Why do transition metals have high melting and boiling points?
A
Because of the attraction between the ions and the delocalised electrons being very strong.
