Explanation:
Detailed explanation-1: -In an alloy, there are atoms of different sizes. The smaller or bigger atoms distort the layers of atoms in the pure metal. This means that a greater force is required for the layers to slide over each other. The alloy is harder and stronger than the pure metal.
Detailed explanation-2: -Pure metals consist of only one type of atom. For example, chromium is on the periodic table of elements, meaning it’s a pure metal. An alloy, by contrast, is a mixture of different atoms melded together.
Detailed explanation-3: -Tungsten, which is Swedish for “heavy stone, ‘’ is the strongest metal in the world. It was identified as a new element in 1781.
