Work Step by Step

This question deals with deciding which figures contain a mixture of two elements. An element contains only one type of atom in it, making it a pure substance. For it to be a mixture of two elements, there needs to be two different types of atoms in the picture, but these atoms can not be chemically bonded. The figures with a mixture of two elements are figures v and vi. These both have more than one pure substance in them, demonstrated by the blue and green atoms in the pictures.
