Apex 3.2 Review - Atomic Models

Why are models useful in the study of atoms?

• Atoms are too dangerous to handle.

• Atoms are too small to see with our eyes.

• Atoms are too big to fit in a lab.

• Atoms are too rare and valuable to use in lab studies.

What are the two main advancements that J.J. Thompson's "Plum Pudding" model proposed?

• Atoms contain smaller particles with a negative charge.

• Atoms are made of negatively-charged particles floating in a positively-charged "sea."

• Atoms are solid spheres.

• Atoms cannot be divided or destroyed.
