Question

the image shows a molecular model of a compound using balls and sticks. each ball is an atom and each stick is a bond. if you were to use balls and sticks to model a molecule of an element, how must your model differ from what’s shown? a. the sticks must be shorter. b. the balls must be the same color. c. the balls must be smaller. d. the balls must change to cubes.

Explanation:

To model an element's molecule, all atoms (balls) must be of the same element, so they should be the same color. Option A (stick length) isn't relevant to element vs compound. Option C (ball size) doesn't determine element. Option D (changing to cubes) is not a standard change for element modeling. Only B aligns with the definition of an element (same type of atom, so same color in the model).

Answer:

B. The balls must be the same color.
