Understanding Atoms and Their Structure

What are the three main subatomic particles that make up an atom?

• Protons, Neutrons, and Electrons

• Electrons, Neutrons, and Quarks

• Protons, Electrons, and Quarks

• Protons, Neutrons, and Photons

How small are atoms described to be in the video?

• Moderately small

• Larger than molecules

• Extremely small

• Visible to the naked eye

If atoms in a grapefruit were the size of blueberries, how big would the grapefruit be?

• The size of the Earth

• The size of a basketball

• The size of a football field

• The size of a house

What analogy is used to describe the number of nitrogen atoms in a grapefruit?

• Atoms in a grapefruit are like drops of water in the ocean

What is found at the center of an atom?

• Protons

• Neutrons

• Electrons

• Nucleus

If an atom were the size of a football stadium, how big would the nucleus be?

• The size of a basketball

• The size of a small marble

• The size of a house

• It is filled with electrons

• It is mostly empty

Where is most of the mass of an atom located?

• In the electrons

• In the protons

• In the empty space

• In the nucleus

How dense is the nucleus of an atom compared to everyday objects?

• As dense as a rock

• As dense as water

• As dense as a car

• As dense as 6.2 billion cars in a one-foot box
