Which of the following images shows
a molecule that is not a compound?
We have been given five images
labeled from (A) to (E). A compound is a substance that
contains the atoms of two or more different elements. Different elements are represented
by different colored circles in the images given. For example, it’s likely that all
the red circles represent the element oxygen. And typically, black is used to
represent carbon.
If we assume that all the circles
of the same color represent the same element, then answer choice (A) is a molecule
containing two different elements. The molecule in (B) contains two
atoms of the same element. And answer choices (C), (D), and
(E) all contain two different elements.
Since we know that a compound
contains two or more different elements and the molecule in (B) only contains one
element, we can determine that the molecule in (B) is not a compound.
Therefore, the image that shows a
molecule that is not a compound is (B).
