What a solid metal consists of
A giant structure of atoms arranged in a regular pattern
What happens to the atoms electrons when they come together to make a solid
They lose their outer electrons and share them with all the other atoms in the metal
What charge the atoms in a metal have
Positive charge
Delocalised electron definition
An electron that is free to move around
The role of electrostatic attractions in a metallic bond
There will be strong electrostatic attractions between the positive ions and the electrons, and these forces of attraction hold the metal’s structure
Properties of a metallic bonded structure
High melting and boiling points, conduct electricity, malleable
Malleable definition
Can be hammered or beat into shape
Why pure metals are malleable
Because of their regular, layered structure which means that their layers can easily slide over each other
Alloy definition
A metal combined with one or more elements
What does an alloy consist of
A mixture of two different metals with differently sized atoms
Why an alloy consists of metals with different sized atoms
Because it disrupts the regular structure so the layers can no longer slide over each other, making the metal harder
