Metal Structures Flashcards
1
Q
What produces all the properties of metals?
A
The free electrons caused by metallic bonds
2
Q
What do we call free electrons?
A
Delocalised
3
Q
What do the free electrons make the metal a good conductor of?
A
Heat and electricity
4
Q
What is the strong force between positive metal ions and negative electrons which allow the atoms to be held in a regular structure?
A
Electrostatic attraction
5
Q
What is an alloy?
A
A mix of two or more metals in order to enhance the property of the metal
6
Q
Why is an alloy harder than a pure metal?
A
Because he different sized atoms cause the regular layers of the alloy to be distorted meaning that it requires more effort for them to be pushed over each other
7
Q
How are metals layed out?
A
Giant structures
