The energy required to remove one electron from an atom in it's gaseous state.
What is ionization energy?
200
Isotopes have the same ____________ properties but different ___________ properties.
Chemical, Physical
200
X(g) → X+(g) + _____
e-
200
Something that measures the mass-to-charge ratio and the relative amounts of ions present in the particle
What is the role of a detector in a mass spectrometer?
200
Relative intensity of each frequency of electromagnetic radiation emitted by the element's atoms or the compound molecules when they are returned to a ground state.
What is an emission spectrum?
300
Matter is composed of discrete units called atoms that are continuously changing.
What is the Atomic Theory?
300
How do the electrons move in an energy level diagram? (in what direction?)
High to Low Energy
300
What is the electron arrangement of Ca?
2.8.8.2
300
The value of the letter n used to describe the levels in an energy level diagram.
What is the principle of a quantum number?
300
Describe the particle that is being deflected in a mass spectrometer. In order to be MORE deflected, what does the particle have to have?
More: High charge, Less mass
Less: Low charge, High mass
400
Something that describes the number of electrons in each main level and it describes how the electrons are distributed in sub-levels.
What is an electron configuration?
400
In a mass spectrometer, the sample must first be ________ either before it is injected into the mass spectrometer or immediately after it has been injected.
Vaporized
400
What is the electron configuration of Ti-22? (Both long and short form)
1s2 2s2 2p6 3s2 3p6 4s2 3d2
[Ar] 4s2 3d2
400
Why are the first ionization energies of the elements not constantly increasing or constantly decreasing but rather random?
Every time an orbital is full, a new orbital is created and the first ionization energies of these elements change depending on which orbital is the orbital being measured.
400
Describe the relation between the Energy levels, the frequency and the wavelength of a wave
As wavelength increases, the frequency and Energy levels decrease as they are inversely proportional to each other due to E = hf
500
This states that when building up an electron structure, the lowest available energy levels are always filled with electrons first.
What is the Aufbau principle?
500
In a mass spectrometer, depending on the _________ and _________ of a particle, its deflection changes.
charge , mass
500

1s2 2s2 2p6 3s2 3p6 4s1 3d10
[Ar] 4s1 3d10
500
States that it is impossible to know the exact position and momentum of an electron.
What is the uncertainty principle?
500
What does the Pauli exclusion principle state?
States that no two electrons in the same atom can have the exact same four quantum numbers.
