What's the Matter?
You must have these two things to be considered "matter".
What is mass and volume?
What are the 3 types of change we have learned about in class?
Physical, chemical, and nuclear change
Who was the FIRST person to say matter's lower limit is the ATOM
Who is Democritus?
What are the 3 subatomic particles?
Protons, neutrons, electrons
Atoms with same number of protons, but different numbers of neutrons.
What is an isotope?
What would be something not considered "matter"?
What is heat, sound, light, etc...?
What would you call the following observations or measurements? Color, malleability, electrical conductivity, smell, density, etc...
PHYSICAL properties
The scientist who discovered the nucleus, protons, AND the 3 different types of radiation.
Who was Rutherford?
What is the charge of all 3 subatomic particles?
protons +1, neutrons 0, electrons -1
Atoms that are unstable go through this process to become stable again.
What is radiation/ radioactivity or nuclear change?
List the types of matter in order from LOWEST energy to HIGHEST
What is solid, liquid, and gas?
In the following chemical reaction: Sunlight + water + carbon dioxide ---> glucose and oxygen, which items are the products?
Glucose and oxygen
Based on the discovery of the electron, JJ Thompson came up with which atomic model?
What is the Plum Pudding Model?
This subatomic particle is the only one that can identify an element.
proton
Atoms that have gained or lost electrons and therefore have a charge.
What is an ion?
What is an element?
What would you call the following observations or measurements: Digestion of food, Banana ripening, Egg frying.
CHEMICAL changes/ reactions
Based on how atoms combine together and separate during chemical reactions, John Dalton illustrated what law?
LAW OF CONSERVATION OF MASS
Give an explanation for why elements have the same number of protons and electrons
Typical elements are neutral and must have equal numbers of protons and electrons in order to balance the positive and negative charges.
What is the mass number of a sodium atom with 12 neutrons?
23
What is the correct order of mixtures based on particle size from LARGEST to SMALLEST.
Suspension, colloid, solution
Come up to the board and DRAW the two types of chemical reactions that we learned about in class.
A + B ---> AB
AB ---> A + B
Come up to the board and DRAW the most current subatomic model, the quantum model, including the proper location of the 3 subatomic particles.
Should show neutrons and protons in the nucleus and electrons outside of the nucleus.
Come up to the board and DRAW a typical lithium atom that has 3 neutrons, including the correct location of all 3 subatomic particles.
Should include inside the nucleus (3 protons and 3 neutrons). Outside the nucleus should be 3 electrons.
Come up to the board and write BOTH names for an oxygen atom with 9 neutrons.
Oxygen-17 and 178O
