Supermodel, You better work!
This is the name of J.J. Thomson's Atom Model.
What is the Plum Pudding Model?
This person's experiments showed that cathode rays were made of small particles
Who is Sir William Crooke?
Dalton's atomic theory said that matter is composed of these very small particles.
What are atoms?
This is who first discovered Brownian Motion.
Who is Robert Brown?
This is what Aristotle believe all matter originated from.
What is hyle?
This is what John Dalton's Atomic Model looks like.
What is an indivisible, uniform, dense, solid sphere?
or
What is a solid, uniform, sphere or ball?
Cathode ray tube technology is used in the earlier forms of this entertainment device.
What are televisions?
Dalton used this law to formulate his theory which says that a compound is composed of the same elements in the same proportion by mass, no matter how small or large the sample.
What is the Law of Definite Composition
or the Law of Definite Proportions?
This is who discovered the electron.
Who is J.J. Thomson?
These radioactive particles are Helium nuclei.
What are alpha particles?
If an atom was as big as an orange, an orange would have to be as big as this.
What is the Earth?
This scientist used cathode ray tubes to see that cathode rays made of negatively charged particles that were attracted to the positively charged plate.
Who is J.J. Thomson?
Dalton used this law to formulate his atomic theory which says that mass is neither created nor destroyed during a chemical reaction.
What is the Law of Conservation of Mass?
This is who conducted experiments and was able to calculate the mass and charge of an electron.
Who is Robert Millikan?
This form of radiation occurs when a neutron changes to a proton and an electron is emitted.
What is a beta particle?
The Scanning Tunneling Microscope or STM led to this type of technology.
What is nano technology?
Cathode ray tubes were used to discover this subatomic particle.
What are electrons?
Dalton used this law to formulate his atomic theory which says that different compounds are formed by a combination of the same elements, but in different whole number ratios.
What is the Law of Multiple Proportions?
This is Democritus's teacher.
Who is Leucippus?
This is the charge of a gamma ray.
What is no charge or zero?
Einstein explained Brownian Motion stating that the movement was a result of these.
What are collisions with molecules or atoms
or
molecular bombardments?
J.J. Thomson found this relationship through his experiments with cathode ray tubes and canceling the electric and magnetic fields exactly.
What is the charge to mass ratio?
These are the 2 revisions of Dalton's Atomic Theory.
What are isotopes and that atoms can be divided, created, and destroyed in nuclear processes?
This person's experimental measurements verified Einstein's explanation of Brownian Motion.
Who is Jean Perrin?
This form of radiation requires 1.5 cm Pb to stop it.
What are gamma rays?
