The Man’s Jeopardy

Learning Objectives 1.Describe the structure of an atom (subatomic particles & their locations and electric charges). 2.Describe elements in terms of their atoms (atomic # & # of protons, isotopes, etc.) 3.Explain how models are useful for studying atoms. 4.Explain how Mendeleev discovered the pattern that led to the periodic table. 5.Describe the data about elements that are found in the periodic table. 6.Predict the properties of elements by using the periodic table.

RULES 1.There will be round robin play and all questions will be all-play. 2.The teams who answers correctly win the point value of the question. 3.If a team answers a daily double incorrectly, then that team will lose the number of points they bid, and other teams can answer correctly to receive the points. 4.There are two daily doubles available. Let’s play

Final Jeopardy The Atom Periodic Table Periodic Trends Elements & Atoms Atomic Misconception

The Atom for 100 All matter is composed of tiny particles that cannot be directly observed called ___________, which scientists study using ___________. Atoms are studied using models.

The Atom for 200 Which particle of an atom has a negative charge? Electron

The Atom for 300 Which part of an atom has no charge? Which particle has a positive charge? Neutron = neutral/no charge Proton = positive charge

The Atom for 400 The center part of an atom that contains 2 of the 3 subatomic particles is called the atom’s __________. Nucleus

The Atom for 500 Describe each part of an atom in terms of its location. Protons and neutrons make up the nucleus, while electrons move around the nucleus in a cloud-like region.

Periodic Table for 100 Mendeleev’s periodic table was organized by increasing _________ __________. atomic mass

Periodic Table for 200 The modern periodic table is organized according to increasing __________ __________. Atomic number

Periodic Table for 300 What piece of information on the periodic table determines the identity of any atom? What does this bit of information tell you about the atoms of that element? Atomic number- tells you the number of protons in the nucleus of the atom of any element

Periodic Table for 400 What’s the difference between groups and periods on the periodic table? Groups are the vertical columns while periods are the horizontal rows.

Periodic Table DAILY DOUBLE! What is the name of the element found in Group 17, Period 3? Also, what is its atomic number, chemical symbol, and average atomic mass? Chlorine, 17 (atomic #), Cl (symbol), and atomic mass units

Periodic Trends for 100 The elements in the same group or column have ____________ properties. similar

Periodic Trends for 200 What can you predict by looking at an element’s location in the periodic table? Its properties

Periodic Trends for 300 Which group of METALS is the most reactive? Group 1

Periodic Trends DAILY DOUBLE!!! Which TWO groups contain the most reactive elements? How do you know? Groups 1 and 17 because as you go down to the left and up and to the right (until Fluorine) you get more reactive elements.

Periodic Trends for 500 Give an element that would have similar properties to (a) Xenon (# 54), (b) Bromine (# 35). Xenon- any element in Group 18 Bromine- any element in Group 17

Elements & Atoms for 100 For a hydrogen-3 atom, what does the 3 represent? Atomic mass of that isotope

Elements & Atoms for 200 What is the specific name given to a chlorine-37 atom? Hint- Examine the number of subatomic particles. It is an isotope of chlorine.

Elements & Atoms for 300 What is the overall charge of a chlorine-35 atom, a chlorine-37 atom, or any isotope? Explain your answer. “0” (no overall charge) because the number of protons and electrons are equal, so the charges cancel out.

Elements & Atoms for 400 How many protons and neutrons does a lithium-7 atom have? Lithium-7 has 3 protons and 4 neutrons.

Elements & Atoms for 500 How many protons, neutrons, and electrons does the most common isotope of oxygen have? What would be the atom’s overall electric charge if it had 2 more electrons? Oxygen-16: 8 protons, 8 neutrons, and 8 electrons (0 overall electric charge) 8+ & 10- equals -2 overall electric charge

Atomic Misconception for 400 What are atoms mostly composed of? Empty space

Periodic Table Using the periodic table, explain why aluminum (Al) is a better choice than magnesium (Mg) or Iron (Fe) for certain real world uses such as boats and house siding. Aluminum would be less reactive than magnesium since it is a metal located to the right of magnesium on the periodic table. So, it won’t undergo chemical change as readily as magnesium would.
