Transcript Elements and the Per. Table Review Game

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 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
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?
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.
