Question

A student creates a ball-and-stick model to represent the atomic scale of a substance. Which of the following best describes the model?

A. 1 molecule with 10 atoms
B. 1 element with 10 molecules
C. 10 molecules representing 10 elements
D. 10 elements representing 10 molecules

Answer 1

Option A. 1 molecule with 10 atoms

Step-by-step explanation:

Each ball in the diagram represents an atom and the stick represents a bond.

A careful look at the diagram of the student's model reveals that the student's model contains 10 balls which represents 10 atoms. This means that a molecule of the student ball-and-stick model contains 10 atoms.

Answer 2

Answer is: A. 1 molecule with 10 atoms.
Every ball represent one atom in one molecule.
The ball and stick model is a molecular model of a chemical substance that shows the three-dimensional position of the atoms and the bonds between them. The atoms have spherical shape and they are connected with sticks (one, two or three, depends on bonds).
