Field
What is a region in which a force is acting, i.e., magnetic fields, gravitational fields, etc.?
This scientist had very humble beginnings as being one of 12 children. When his father died, his family moved him to Moscow with the hopes of furthering his academic career. He is known for his periodic table of elements.
Who is Dmitri Mendeleev?
The discovery of Oxygen
What was done in part by Priestley when he played around with the substances from the vats of beer in the local pub as well as being done through experiments of Antoine Lavoisier?
What is answers may vary, but all answers should have the protons and neutrons in the nucleus and the electrons in orbitals surrounding the nucleus?
The three subatomic particles in an atom, their charge, and who discovered them
What are the proton (+) discovered by Rutherford, the neutron (neutral) discovered by Chadwick, and the electron (-) discovered by Thomson?
Heterogenous mixture
What is a substance in which we can see the individual components that have been physically combined?
Created the quantum model of the atom which suggested that atoms can act like both particles and waves. He created out most modern understanding of the atomic model.
Who is Erwin Schrodinger?
J.J. Thomson's Cathode Ray Tubes
What are the pieces of equipment he used to determine that the negative charges in the atom were the electrons which existed in a positively charged background?
The field line diagram for a magnetic field
What is the magnet with North and South poles with lines drawn from the north to the south poles. Lines should go out from the ends of the magnet as well?
Difference between the solute and the solvent
What is the solute is what is being dissolved vs. the solvent is what is doing the dissolving?
Radioactive Isotope
What is an isotope, which is an element with a different number of neutrons than the normal element, which exhibits radioactive properties?
This scientist often displayed his scientific achievements in front of large groups. He also discovered different gases like laughing gas through self-experimentation. He later went on to do work with electrolysis.
Who is Humphrey Davy?
The Gold Foil Experiment
What is the experiment completed by Ernest Rutherford in which alpha particles were fired at a gold foil in order to determine if Thomson's model was correct or not. It proved that the center of the atom was the positively charged nucleus.
3 ways you are exposed to radiation and how to reduce your risk to each way.
What are __________? Answers may vary
The three types of fields covered in this class as well as what affects them, where they are, and what force is present
What are the electric fields which are around the subatomic particles causes by electricity and are affected by charges; the magnetic fields which are around magnets, affected by magnets and current-carrying wire and magnetism; the gravitational fields around things with mass, affected by mass and the force of gravity?
The Right Hand Rule and show me what this looks like with your hand
What is a physical representation of how the magnetic field is moving around a current carrying wire? The thumb is the motion of the field, the index finger is the direction of the field, and the middle finger is the induced current.
The two scientists who helped us with our understanding of gravitational fields and what they told us.
Kepler- planets move in elliptical orbits; the size of planets is proportional to the size of their orbits; no matter the size of the orbit, a planet travels at the same speed no matter the place in the orbit.
Newton- 2nd law of motion F = ma
The discovery of the neutron
What is the results of experiments done by James Chadwick although interrupted by WWI?
The four main parts of every element square on the Periodic Table of Elements and their definitions
What are the atomic number (the number of protons and electrons on a neutral atom), the Chemical symbol (short-hand way to write the element in chemical reactions), the element name (named for the scientist who discovered it, where it was discovered, etc.), and the mass number (the average mass of all of the isotopes for that element)?
4 Examples of everyday uses for magnetism and how they use magnets
What is the mass of the reactants in a chemical reaction must equal the mass of the products in a chemical reaction?
The order of our scientists from the Mystery of Matter
What is as follows:
Brandt --> Cavendish --> Priestley --> Lavoisier --> Davy --> Mendeleev --> Curie --> Moseley --> Seaborg
The oil drop experiment
What is the experiment completed by Robert Millikan, it involved the use of an atomizer dropping oil onto charged plates until an isolated electron could be found. The electron has a negative charge, which Millikan was able to evaluate and determine how much charge was present.
Dalton's five tenets
What are as follows:
1) all substances are composed of tiny, indivisible particles known as atoms.
2) all atoms of the same element are identical
3) atoms of different elements have different weights
4) atoms combine in whole number ratios to make compounds
5) atoms are neither created nor destroyed in chemical reactions
All of the groups on the Periodic Table, Name, Group Number, and 1 Element in that group
Group 1 Alkali metals Sodium; Group 2 Alkaline Earth metals Calcium; Group 3-12 Transition metals Iron; Group 17 Halogens Bromine; Group 18 Noble Gases Neon; Lanthanides Top Cerium; Actinides Bottom Uranium
