Question

Use the diagram that depicts a model of a molecule containing carbon and hydrogen to answer the question.
Which statement best describes a correct use for this model?
(1 point)
to determine the mass for the compound
to see the relative size differences between the atoms and the compound
to determine the relative distances between electrons and the nucleus
to see the charge density distribution of the electrons

Answer 1

to see the relative size differences between the atoms and the compound

Explanation: molecular models show atom sizes, relative atomic radii and molecular shape/arrangement. They do not give mass, detailed electron–nucleus distances, or charge density distributions.
