Explain how the analogy of a single brick or lego helps you understand what an atom is.

Multiple Choice

How does the analogy of colored bricks or legos help explain the concept of an element in chemistry?

• Each colored brick represents a different element, just as each element is unique.

• Bricks can only be used for building houses, just like elements can only form compounds.

• Bricks are always the same color, just like all elements are the same.

• Bricks cannot be combined, just like elements cannot form molecules.
