Final Jeopardy Atomic Theory

Final Jeopardy What is indivisible (not able to be divided) units? Democritis named the atom after the Greek word “atomos” which has this meaning.

$200 What is 8 (14 - 6 = 8)? The number of neutrons in Carbon-14.

$400 What is the number of neutrons? The difference between isotopes of the same element is this.

$600 What is the have the same numbers of protons and electrons because they are from the same element? These are the two things that isotopes have in common.

$800 Calculate the number of protons, neutrons, and electrons for B-10 and B-11.

$1000 What is 241. 67 amu? You have discovered a new element and have named it Neptunite. While studying your new element, you find that it has three isotopes—Neptunite– 220, Neptunite– 250, and Neptunite-255. This is the average atomic mass of your new element. (Assume that these three isotopes are present in equal amounts in nature. )

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

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

$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?

$800 What is neon? Which element is electrically neutral? Element # of Protons # of Electrons Fluorine 9 10 Neon 10 10 Sodium 11 10 Magnesium 12 10

$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 many of these dots an element in Group 15 would have.

$200 What are periods? The name given to the horizontal rows on the Periodic Table.

$400 Who is Dimitri Mendeleev? The name of the chemist who organized the known 63 elements at the time by increasing atomic weight and shared properties into a Periodic Table. He did this in 1869.

$600 What are groups or families? The vertical columns on the Periodic Table are called these and are arranged in a manner that the elements in these columns have similar chemical and physical properties.

$800 What is Uranium (U)? The element that is in Period 7 and is considered radioactive because of its large, unstable nucleus. It was one of the fuels used to construct the early atomic bombs in the WWII era.

$1000 What is Gold (Au)? The name of the precious metal that is in Group 11 and Period 6. It is classified as a transition metal.

$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”.

$400 What are Alkaline Earth 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.

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

$800 • • Ar • • Draw the correct Bohr model for Argon (Ar) by determining its protons, neutrons, and electrons. Draw its Lewis structure also.

$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.

$200 What are electrons? 2, 8, 18, 32 Each energy level of an atom has a maximum number of ____ it can hold. Do you remember the numbers?

$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

$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

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

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

$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.

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

$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.

$800 What is Cl-35 and Cl-37 are both forms of Chlorine with 17 protons and 17 electrons and they differ in that Cl-35 has 18 neutrons while Cl-37 has 20 neutrons? Compare Cl-35 to Cl-37.

$1000 What is 40. 0 g? Three students weigh an item using different scales. These are the values they report: a. 20. 03 g b. 20. 0 g c. 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.

Daily Double What is Cl-35 and Cl-37 are both forms of Chlorine with 17 protons and 17 electrons and they differ in that Cl-35 has 18 neutrons while Cl-37 has 20 neutrons? Compare Cl-35 and Cl-37.
