Other questions in this quiz

2. Why are alloys stronger and harder than pure metals?

  • Different sized atoms disrupt the regular arrangement of atoms and so the layers cannot slide over each other.
  • Different types of free electrons repel each other and so keep the metal in a certain shape.
  • The added metal is harder than the original metal.
  • The atoms are now bigger so there is less room to move.
