Problem

Let a small circle represent an atom of one type of element and a small square represent an atom of a second type of element. Select what is shown on each of the pictures:

A collection of small circles and squares where the circles are on one side of the sample and the squares on the other. The circles represent an atom of one type of element and squares represent an atom of a second type of element.

(a) a pure substance (a compound) composed of the two elements (in a one-to-one ratio)
(b) a homogeneous mixture composed of the two elements
(c) a heterogeneous mixture composed of the two elements
