Essential Chemistry for IGCSE - Metals And Reactivity (Section 5 - No. 4)
What is the key difference in the arrangement of atoms in an alloy compared to a pure metal?
Alloys have a more ordered arrangement.
Alloys have a random arrangement.
Alloys use different-sized atoms, disrupting the regular structure.
Alloys are only made of one type of atom.
Explanation
Alloys typically contain different-sized atoms, which disrupt the regular arrangement of the atoms in the metal's crystal structure, affecting its properties.
