|
Metals consist of giant structures of atoms arranged in a regular pattern. |
|
What is the structure of a metal like? Get students to draw out two metal ions and think about how they could bond together, ensuring each gets a full outer shell of electrons. |
|
|
|
The electrons in the outer shell of metal atoms are delocalised and so are free to move through the whole structure. |
|
How are the electrons in the outer shell of metal atoms arranged? Input: Show students how metals actually bond.
use the equipment to show how the atoms arrange themselves into neat rows. add water to represent the delocalised electrons saying that the water can move freely. |
|
|
|
The sharing of delocalised electrons gives rise to strong metallic bonds. The bonding in metals may be represented in the following form: (diagram) |
|
Why are metallic bonds so strong? Give students a piece of metal each and get them to describe the properties it has.
Input Feedback to how the structure of the metal gives it those properties. |
|
|
|
Students should be able to recognise substances as metallic giant structures from diagrams showing their bonding. |
|
Describe the structure of metallic bonding? |
|
|
|
Students should be able to recognise that atoms themselves do not have the bulk properties of materials |
|
When compared with the properties of materials, do atoms have the same bulk properties? |
