Unit 2 Test Review
Questions
What is radioactive decay?
This slow moving decay particle
has 2 protons and 2 neutrons, just
like the nucleus of a helium (He)
atom.
This fast decay particle can be
stopped by aluminum foil or wood
and it consists of an electron.
This highly dangerous decay
particle has no mass and is only
partially stopped by 6 inches of
lead or 6 feet of concrete.
What is fisison?
What is fusion?
Which process creates more
energy: fission or fusion?
Name 3 places where fission is
used.
Name 2 places where fusion is
used.
How does a nuclear fission reactor
work?
What is Bohr's model of the atom?
What is the quantum mechanical
model of the atom?
How many energy levels are
possible in an atom?
Name the 4 types of sublevels.
How many electrons can fit in an s
sublevel?
How many electrons can fit in a p
sublevel?
How many electrons can fit in a d
sublevel?
How many electrons can fit in an f
sublevel?
What is the shape of an s sublevel?
What is the shape of a p sublevel?
What is the electron configuration
for boron, B?
What is the electron configuration
for Titanium, Ti?
Does an electron act as a particle
or a wave?
What is the relationship between
wavelength and frequency of a
wave?
What speed does visible light and
all other electromagnetic radiation
travel?
Which color of light in the
spectrum (rainbow) has the largest
wavelength?
Which color of light in the
spectrum (rainbow) has the
highest frequency?
What is the wavelength of
ultraviolet light that has a
frequency of 3.00 X 1014 1/s?
What is the energy of ultraviolet
photons being emitted if the
frequency is 3.00 X 1014 1/s?
How can you identify an element
based on the idea of electrons
moving and the color of light
emitted?
How many protons, electrons, and
neutrons are in 10847Ag?
What is the density of a substance
that has a mass of 72.45g and a
volume of 18.654mL? (d=m/V)
Which element has the largest
atomic radius (size) and which has
the smallest?
This scientist was the first to
develop the theory that everything
is made of atoms.
This scientist developed a theory
that states that all elements are
made of atoms, that atoms of
elements are identical, and
elements combine in simple,
whole-number ratios.
Completed the cathode ray
experiment and discovered
electrons
Performed the gold foil
experiement with alpha particles
and ultimately discovered the
nucleus, protons and neutrons
This scientist developed a model of
the atom that resembles the
planets orbiting the sun. It has
electrons orbiting the nucleus.
This model, developed by Erwin
Schrodinger, states that electrons
move around the nuclus within
electron clouds, 90% probability
areas.
The number of protons in the
nucleus of an atom is also known
as….
What is Mass Number?
What is an isotope?
How many protons, electrons, and
neutrons are in an atom of
20080Hg?
Carbon has two isotopes: one has
a mass of 12.000amu with a %
abundance of 98.93% and the
second has a mass of 13.003amu
and a % abundance of 1.07%.
What is the atomic mass?
How many protons, electrons, and
neutrons are in an atom of
7232Ge?
