What did people put for the structure of an alloy compared to a pure metal?

I said:
-It has different elements which have different sized atoms
-This distort the layers in the mixture and prevent them from sliding over each other.

Is that right? :frown:

That should be right, I completely forgot the word distort in the exam and started thinking of words beginning with d. I ended up putting that the layers are deranged and that doesn't really make sense. I did say that the layers can't slide though so hopefully I will still get the marks.

SOMEONE PLEASE TELL ME:

What was the answer for the C2 6 Marker??
What were the key points about the trends?

The B2 and C2 6 markers have been so unscientific which has been pretty annoying;/
