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.

Answer 1

Answer: Option (B) is the correct answer.

Explanation:

An element contains atoms with same atomic number. This means that each atom of an element will have same number of protons.

For example, in oxygen element all atoms of oxygen will have atomic number 8.

Thus, we can conclude that if you were to use balls and sticks to model a molecule of an element, then the balls must be the same color.
