Which of the following molecules contains the greatest number of elements?
A molecule is a group of atoms bonded together. The atoms that make up a molecule may be of the same element or different elements. In the figures, circles that are the same color represent atoms of the same element. And circles that are a different color represent atoms of different elements. In these figures, red circles often represent the element oxygen and black circles often represent the element carbon.
To determine which of the molecules has the greatest number of elements, we need to identify the figure that has the greatest number of differently colored circles. Looking at the answer choices, we can see that figure (C) has the greatest number of differently colored circles. Therefore, the molecule that contains the greatest number of elements is the molecule shown in answer choice (C).
