Metals consist of what type of structure?
giant
1 of 17
Of _______ in a ______ pattern?
atoms in a regular pattern
2 of 17
Electrons in the outer shell of metal atoms are?
delocalised
3 of 17
This means they are free?
to move throughout the whole structure
4 of 17
Due to the sharing of delocalised electrons?
they have very strong electrostatic forces
5 of 17
These form strong?
metallic bonds
6 of 17
What state are they at room temp?
solid
7 of 17
They have high?
melting and boiling points
8 of 17
They are good?
conductors of heat and electricity
9 of 17
In pure metal, how are the atoms arranged?
in layers that slide over each other
10 of 17
This makes them?
malleable
11 of 17
However pure metals are sometimes?
too soft for certain jobs
12 of 17
And are therefore?
mixed with other metals or elements
13 of 17
This forms an ?
alloy
14 of 17
What is an alloy
a mixture of two or more metals or elements
15 of 17
This makes them?
harder
16 of 17
Why?
since different elements/ metals have different sized atoms. This disrupts the layers making it difficult for them to slide over each other making it hard
