The Basic Structure of the Atom

What does nature use to create larger structures?

• A single type of component in large quantities

• Collections of a few smaller types of components

• Complex machinery and technology

• Random assembly without specific components

What happens when an atom of gold is divided?

• It remains gold regardless of division

• It disappears completely

• It turns into a different element

• It turns into silver

What are atoms made of?

• Only protons

• Only electrons

• Atoms cannot be divided into smaller parts

• Protons, electrons, and neutrons

Who is credited with the discovery of the electron?

• John Dalton

• JJ Thomson

• Ernest Rutherford

• James Chadwick

Why did the beam curve like seen in the image?

• The negative electrons are attracted the positive plate and repelled by the negative plate

• The positive electrons are attracted the positive plate and repelled by the negative plate

• The negative electrons are attracted the negative plate and repelled by the positive plate

• The negative electrons are attracted the negative plate and repelled by the plate postive

What model did Thomson propose for the atom?

• Plum pudding model

• Solar system model

• Nuclear model

• Quantum mechanical model

What did the Rutherford conclude when he saw this result.

• Atoms are made up of mostly empty space but with a highly concentrated nucleus containing almost all of the atoms mass

• Atoms are made up of mostly solid space but with a highly concentrated nucleus containing almost none of the atoms mass

• Atoms are made up of mostly empty space but with a highly concentrated nucleus containing only a fraction of the atoms mass

• Atoms are made up a highly concentrated nucleus containing almost all of the atoms mass
