Whose model is this and what did he call it?
$100 Answer from H1
J.J. Thomson – Plum Pudding
$200 Question from H1
This scientist could be found in
Wal-Mart, checking out the gold foil.
Who is the scientist and what particle
did he discover?
$200 Answer from H1
Rutherford – the proton
(and the nucleus)!
$300 Question from H1
This is the most current model of the atom.
$300 Answer from H1
The Quantum Mechanical model
AKA the electron cloud model.
$400 Question from H1
A mathematician, this man discovered
the neutron due to a mass variation.
$400 Answer from H1
James Chadwick discovered the neutron.
$500 Question from H1
Atoms cannot be created nor destroyed.
This statement is true according to this
early atomic theorist.
$500 Answer from H1
John Dalton
$100 Question from H2
In a chemical reaction, the mass of the
products equal the mass of the reactants.
This is a statement of which law?
$100 Answer from H2
The Law of Conservation of Mass
$200 Question from H2
This principle says electrons
fill from the lowest available energy level.
$200 Answer from H2
Aufbau
Actually means “building up” in German
$300 Question from H2
Sometimes electrons get excluded because
only two can fit in an orbital, according to
this principle.
$300 Answer from H2
Pauli Exclusion Factor
$400 Question from H2
According to this law, any two samples of KCl
will have the same elements in the same
proportion by mass.
$400 Answer from H2
Law of Definite Proportions
$500 Question from H2
The two oxides of iron, Fe2O3 and FeO,
are explained by which law?
$500 Answer from H2
Law of Multiple Proportions
$100 Question from H3
Classify as a Metal/Nonmetal/Metalloid:
Sodium
$100 Answer from H3
Metal
$200 Question from H3
How many valence electrons does sulfur have?
$200 Answer from H3
Six
$300 Question from H3
True or False:
The mass number is listed on the periodic table.
$300 Answer from H3
False. The mass number is the
number of protons plus the number
of neutrons. It is typically fairly close
to the average atomic mass.
$400 Question from H3
What is an ion?
$400 Answer from H3
Any atom that is not neutral.
$500 Question from H3
Find the P-E-N for the above isotope.
$500 Answer from H3
Protons = 74
Electrons = 74 (no charge)
Neutrons = 109 (183-74)
Double Jeopardy (make a wager):
How many electrons would the
Atom have if it had a charge of +7
$100 Question from H4
What is the core notation for Br?
$100 Answer from H4
[Ar] 4s23d104p5
$200 Question from H4
How many orbitals does the p sublevel have?
$200 Answer from H4
Three
$300 Question from H4
What is the longhand electron
configuration for N?
$300 Answer from H4
1s22s22p3
$400 Question from H4
What is the core notation for Lead?
$400 Answer from H4
[Xe] 6s24f145d106p2
$500 Question from H4
What rule is being broken in the following
electron configuration.
Be specific as to why:
1s3
$500 Answer from H4
S has only one orbital – according to Pauli,
you cannot have more than two electrons
in an orbital. The example has three
electrons in one orbital.
$100 Question from H5
Draw the Lewis Structure for Cl.
$100 Answer from H5
$200 Question from H5
Helium has two isotopes: Helium-3 and
Helium-4. Which isotope is more abundant,
given that the atomic mass of helium is
4.0026 amu?
$200 Answer from H5
Helium-4, the mass is closer to the value of
the average atomic mass listed on the
periodic table.
$300 Question from H5
Boron has two isotopes: Boron-10
(atomic mass of 9.998 amu, percent
abundance = 19.9%) and Boron-11
(atomic mass of 11.02 amu, percent
abundance = 80.1%).
What is the average atomic mass of boron?
(SIG FIGS!)
$300 Answer from H5
10.8 amu
$400 Question from H5
Atomic radii is best described as
A. An element’s ability to attract electrons
B. One-half the distance between the nuclei
of identical atoms that are bonded together
C. The energy required to remove one
electron from a neutral atom
D. The outermost level of electrons
$400 Answer from H5
Atomic radii is best described as
B. One-half the distance between
the nuclei of identical atoms that
are bonded together
$500 Question from H5
Ionization energy tends to decrease as you
go down a group in the periodic table. This
is due to the effects of
A. Parent protons
B. Increasing Electron Shielding
C. Increasing Effective Nuclear Charge
D. The Quantum Effect
$500 Answer from H5
Ionization energy tends to decrease as you
go down a group in the periodic table.
This is due to the effects of
B. Increasing Electron Shielding
