The Man’s Jeopardy

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

RULES There will be round robin play and all questions will be all-play. The teams who answers correctly win the point value of the question. 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. There are two daily doubles available. Let’s play

The Atom for 100 Semiconductors are elements that are also called metalloids. They are called semiconductors why? They only conduct heat and electricity under certain conditions.

The Atom for 200 Magnesium is to the right of sodium because it has more or less protons More

The Atom for 300 Why did Mendeleev leave blank spots in his periodic table? For unknown elements

Group 1, 1 valence electron The Atom for 400 Why are the elements: potassium, lithium, hydrogen and sodium so reactive? Group 1, 1 valence electron

The Atom for 500 Elements in a family have: Similar chemical properties

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 35.45 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?

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
