brain pop atomic model

How do scientists know how atoms are structured?

• by looking at them under a microscope

• by running experiments that expose their properties.

• by examining only the largest atom

• by splitting them apart

What can you conclude from the fact that scientists continue to update the atomic model?

• new information continues to be discovered.

• old information is completely useless.

• scientists did not have any information about atoms until a few years ago.

• scientists still have no idea what atoms look like.

What contribution did John Dalton make to atomic theory?

• he discovered that every atom was positively charged.

• he discovered that every element consisted of one type of atom.

• he discover that atoms have nuclei

• he discovered that atoms can be broken down into smaller parts.

• he discovered that Mr. Falabella was smarter than him :)

Place the following scientists in order, from earliest to latest: A) Ernest Rutherford; B) J.J. Thomson; C) John Dalton

• B,C,A

• C,A,B

• A,C,B

• C,B,A

The majority of an atom's mass exists where?

• the Nucleus

• the electron cloud

• in the space between the nucleus and electrons

• in the neutrons

What are electrons?

• postoperative charged partials

• Negatively charged partials

• Neutrally charged partials

• uncharged partials

Ernest Rutherford discovered that atoms were mostly:

• Negatively charged

• Positively charged

• Electrons

• Empty space

What does the nucleus of an atom contain?

• Electrons and Neutrons

• Protons and Neutrons

• Neutrinos and Positrons

• DNA and RNAs

• Dad Jokes and Angry Kids

How are neutrons different from protons and electrons?

• they are more massive then protons and electrons

• they have no electrical charge

• they are less massive the protons and electrons

• protons and electrons exist in the nucleus, while neutrons exist in the cloud.

How are electrons arranged in an atom?

• in groups of 5

• in energy levels

• by color

• by shape

• in a lightning bolt configurations (dad joke of the day.... get it, because they electric lolololol :)
