  1. Final Jeopardy Atomic Theory

  2. Final Jeopardy What is indivisible units? Democritis named the atom after the Greek word atomos which has this meaning.

  3. $200 What is 79.3 or 79.4 grams? What is this object’s mass in grams?

  4. $400 What is by calculating the density using the formula density = mass ÷ volume or by measuring the mass and volume of each product? This is how I could scientifically explain through the objects’ density why the Coke sank and the Diet Coke floats.

  5. $600 What is 2.7 cm? What is the length of the line in cm?

  6. $800 What is 6.6 mL? What is the volume in mL?

  7. $1000 What is 0.8 mL? The volume of this irregularly shaped dinosaur is ________ .

  8. $200 What is the electron? The particle that moves around the nucleus is called the __________ .

  9. $400 What is Hydrogen? This element in the table above has the lowest mass number.

  10. $600 What is 6 (to be neutral, have to have same # of protons and electrons? An atom has 6 protons and 8 neutrons and is electrically neutral. How many electrons does the atom have?

  11. $800 What is neon? Which element is electrically neutral?

  12. $1000 What are valence electrons? Any element in group 15 would have 5 dots. Lewis structures show the number of _______ _______ in a particular element. Show how many of these dots an element in Group 15 would have.

  13. $200 What is an inference? Deer live nearby in the woods.

  14. $400 What is an inference? The men are tired.

  15. $600 What is an observation? The tree with the fire in the cavity has no bark.

  16. $800 What is an inference? The woman on the ground is dead.

  17. $1000 What is an inference? The woman fell from the white horse.

  18. $200 What is form compounds? The alkali metals, found in group 1 of the periodic table are metals that do not occur freely in nature. These metals have only one valence electron in their outer shell. Therefore, they are ready to lose that one electron in ionic bonding with other elements very easily. This makes them _______ _________ especially with group 17 because they have 7 valence electrons and when the two combine they make the magic number “8”.

  19. $400 What are alkaline earth elements/metals? The ____________ elements are metallic elements found in the second group of the periodic table. They all contain 2 valence electrons in their outermost energy level.

  20. $600 The Boron family or group 13. These elements have 3 valence electrons and are called the _______ family.

  21. $800 What is (C.) or region 3? • The following graph shows the change in temperature of a sample of H2O, which begins as ice, as thermal energy is added. • Which region of the graph represents water (H2O) in the liquid form only? • A. 1 • B. 2 • C. 3 • D. 4

  22. $1000 What is change over time as new things are discovered? The early work of Democritus (indivisible atoms), Dalton (atoms are solid spheres), Thomson (Plum pudding model), Rutherford (planetary model), and Bohr (electrons are in shells around the nucleus) in relation to the views on atomic theory have led us to the current belief that electrons are found in clouds around the nucleus (Electron Cloud Model). This shows an example of how scientific theories can __________ when new things are discovered.

  23. $200 What are electrons? Each energy level of an atom has a maximum number of ____ it can hold. Do you remember the numbers?

  24. $400 What are D. valence electrons? • Lewis dot diagrams are used to represent what? • A. atomic number • B. isotopes • C. structure of the nucleus • D. valence electrons

  25. $600 What are the number of protons (B.)? • These are always the same for all of the atoms of a particular element. • A. isotope • B. number of protons • C. number of neutrons • D. number of electrons

  26. $800 What are isotopes? Atoms of the same element with different numbers of neutrons are called ___________.

  27. $1000 What is 56 (protons + neutrons = mass number)? If an element has 26 protons, 26 electrons, and 30 neutrons, what is its mass number?

  28. $200 What are chemical splash goggles and chemical resistant gloves? These are two types of safety equipment that you should always wear if you are working with strong acids.

  29. $400 What is a theory? • A statement that explains natural phenomena is known as a _______________ .

  30. $600 What is same, different, and chemically? In an element, (pure substance) the atoms are the _______. In a mixture, the atoms are _______ and not ________ combined.

  31. $800 What is Y, X, Z, and W? Rank the density of the unknown liquids from least to most dense.

  32. $1000 What is 40.0 g? • Three students weigh an item using different scales. These are the values they report: • 20.03 g • 20.0 g • 0.0023 g • The students enter the numbers on the calculator, and the answer is 40.0323 g. Show the answer with the properly rounded number of significant figures.

  33. Daily Double What is Y, X, Z, and W? Rank the density of the unknown liquids from least to most dense.
