Answer : The three true statements are,
- They’re harder than the pure metals they’re made of.
- They’re good conductors of electricity.
- They have a metal as their main component.
Explanation :
Alloys : They are the metallic compound that made up of the one metal and one or more metals or non-metal elements. In the alloy, metal is the major element.
Some examples of alloy are, steel that is the combination of iron and carbon, brass is the combination of copper and zinc, bronze is the combination of copper and tin.
There are some properties of the alloys :
- They are made from metals combined in different amounts.
- They are harder than the pure metals they are made of.
- They are harder but not brittle.
- They are the good conductor of electricity.
- They have a metal as their main component.
