What are valence electrons?
Electrons on all energy levels of an atom
Electrons on the outermost energy level of atom
Electrons on the innermost energy level of an atom
Electrons on the mid-section of an atom
5
What is Wavelength?
A new Brand of Athleisure Clothing
A person's ideas and way of thinking
The distance between successive crests of a wave
A distinctive feature of radio waves from a transmitter
6
What did Erwin Schrodinger contribute to Atomic Theory?
He developed the Electron Cloud Model.
Discovered the Protons.
Made the Bohr Model.
None of the Above.

10
Max Planck proposed that a hot object radiated energy in small, specific amounts called
electrons
Llama
waves
quanta
11
Niels Bohr's model states that
the atom is mostly empty space
all of the above
electrons move in orbits
the nucleus contains protons and neutrons
12
The Aufbau principle states that...
Max 3 Electrons per Shape/Orbital
Every orbital on an energy level needs an electron.
Electrons must be paired with opposite spins.
The lowest available energy level is filled first.
13
If electrons in an atom have the lowest possible energies, the atom is in the
radiation emitting state
ground state
intert state
excited state
14
The number of orbitals/shapes for the
f
sublevel is
1.

7.
15
What is the frequency of a wave?
how many troughs a wave has
how often the wave goes up and down past a certain point
the color of a wave
the orbit of the wave
16
How many electrons can occupy the
s orbitals
at each energy level
two, if they have opposite spin
no more than 8
two, if they have the same spin
one
17
The electron config of potassium is?
1s2 2s2 2p6 3s2 3p6 4s2
1s2 2s2 2p6 3s2 3p6 4s1
None of them are correct :(
1s2 2s2 2p6 3s2 3p6
18
The Pauli Exclusion Principle says:
Electrons fill the lowest energy level first
Electrons in the same orbital must have opposite spins
Only 2 electrons can occupy an orbital
Electrons will spread apart within an orbital if they can
19
What does the principle quantum number identify?

Orbital Shape
Orientation
Energy Level
20
What is the electromagnetic spectrum?

[Kr] 6s2 5d10
[Kr] 5s2 4d10
Cd
[Kr] 5s2 5d10

23
Which orbital diagram shows an
Aufbau
violation
?
c
a
d
b
24
Hund's Rule...
No Idea
the answer is not there
occupy every orbital with 2 as you go
Each Shape fills with 1 electron before a 2 electron is added
25
What is the Heisenberg Principle?
People want to appear happy to the rest of the world.
The mere act of observing something alters it.
Breaking Bad
Pinging subjects throughout the day.
26
Shorter the wavelength the...
Higher the frequency
Lower the frequency
The more likely the wave explodes
Frequency stays the same
