Atomic Theory
Studying the early atomic theory
| Question | Answer |
|---|---|
| This man was known as the "Laughing Philosopher". | Democritus |
| He stated that "Compounds are formed by a combination of two or more different kinds of atoms." | John Dalton |
| Who developed the Plum Pudding Model? | J.J. Thomson |
| Who discovered protons? | Eugen Goldstein |
| Who discovered the neutron? | James Chadwick |
| Subatomic particle with no charge. | Neutron |
| Protons + neutrons = ? | Mass number |
| What do we call an atom whose mass has changed? | Isotope |
| What do we call and atom that has more electrons than protons? | Anion |
| What model has no subatomic particles? | Indivisible sphere |
| What experiment was used to find both protons and electrons? | Cathode Ray Tube |
| What was the last subatomic particle to be discovered? | Neutron |
| Which scientist did not perform any experiments? | Democritus |
| Who stated that "A chemical reaction is a rearrangement of atoms"? | John Dalton |
| Who discovered electrons? | J.J. Thomson |
| Which scientist was a party animal? | Ernest Rutherford |
| Who developed the Nuclear Atomic Model? | James Chadwick |
| Subatomic particle with a negative charge. | Electron |
| Number of protons = ? | Atomic number |
| Weighted average of isotopes. | Average atomic mass |
| These are "paws-itive". | Cations |
| Which model includes neutrons? | Nuclear atomic model |
| Which model shows electrons orbiting around the nucleus? | Planetary model |
| Has mass but no charge. | Neutron |
| Opposite charges will... | Attract |
| Which experiment did Rutherford perform? | Gold Foil |
| What model of the atom did J.J. Thomson propose? | Plum Pudding |
| A-Negative-Ion | Anion |
| Which experiment did Millikin perform? | Oil Drop |
| More protons than electrons. | Cation |
| Average atomic mass is a(n): | Weighted average |
| When protons = electrons the atom is: | Neutral |
| When the number of neutrons has changed the atom is called a(n): | Isotope |
| When protons do not equal electrons the atom is called a(n): | Ion |
| Which subatomic particle was discovered first? | Proton |
| Where do protons and neutrons exist? | Nucleus |
| Subatomic particle with a positive charge. | Proton |
| Who discovered the mass and charge of an electron? | Robert Millikin |
| Who performed the Gold Foil experiment? | Ernest Rutherford |
| Which scientist used a Cathode Ray Tube: John Dalton, Ernest Rutherford, J.J. Thomson, or James Chadwick? | J.J. Thomson |
| Which scientist is relatively unknown because he didn't get along well with others? | Eugen Goldstein |
| Who performed the Oil Drop Experiment? | Robert Millikin |
| Who discovered the nucleus? | Earnest Rutherford |
| Who formulated hypotheses and theories and performed experiments to explain his theories? | John Dalton |
| Who proposed the Indivisible Sphere model of the atom? | Democritus |
| Who is the Father of the Atomic Theory? | John Dalton |
| Who was the first to assign symbols to elements and compounds? | John Dalton |
