1. Draw a model molecule and
label:
• Protons, Neutrons, Electrons
• Quarks (up and down)
• The actual Molecule
• An Atom
2. Rutherford did an experiment to
prove that atoms were actually
made of what?
EMPTY
SPACE
3. According to the
Rutherford model of the
atom what does an atomic
nucleus contain?
Compared to a proton, what is
the mass and charge of an
alpha particle?
Charge = +2
Mass = 4-amu
When an electron changes from a
higher energy to a lower energy
state within an atom, what
happens?
A hydrogen atom in the
ground state receives 10.2
eV of energy. To which
energy level will this
become excited?
Using your Ref. Table
What is the minimum energy
required to excite a mercury
atom initially in the ground
state?
Find the difference in energy between the
ground state and the first level
(-10.38)- (-5.74) = -4.64 eV
What series involved electrons
jumping to the first energy level?
A hydrogen atom emits a 2.55-eV
photon as its electron changes
from one energy level to another
11. Express the energy emitted in Joules
4.08 x 10 -19 Joules
12.Determine the frequency of the emitted
photon.
6.154 x 1014 Hertz
13.What was the energy level change for the
electron?
It jumps from 4 to 2
Which of the two groups of
elementary particles are made of
quarks?
What is the most massive
hadron?
All elementary particles have a
corresponding anti-particle.
What is an antiparticle?

charge of +1 and a quark
combination:
•

su (with a line over the u)
ds (with a line over the s)
dc (with a line over the c)

25. Quarks are made of little
mathematical ________ that allow
for their different characteristics
26. Although string theory does
explain everything, it is not a
proven law because . . . .
It cannot be tested
27. Einstein’s Law of special
relativity says:
• As something approaches the speed of
light, its mass _________
• As something approaches the speed of
light, relative to an outside observer, time
_________
28. What are three products of a
fission reaction?
1. Possibly radioactive elements
2. Neutrons that cause a chain reaction
3. energy
29. What are the products of a
Fusion reaction?
1. Alpha particles (Helium nuclei)
2. ENERGY
