What is a proton?
100
These are atoms of the same element that have the same atomic number but different mass numbers due to differing numbers of neutrons.
What are isotopes?
100
True or False: Every element gives off a unique atomic emission spectrum that can be used to identify it.
What is True?
100
This dumbbell/peanut-shaped subshell contains 3 orbitals and can hold a maximum capacity of 6 electrons.
What is the p subshell?
100
These electrons are located in the outermost principal energy level and dictate an atom's reactivity and chemical bonding.
What are valence electrons?
200
Found on the periodic table, this value equals the number of protons in an atom and determines the identity of the element.
What is the atomic number?
200
The weights of these two subatomic particles contribute to the atomic mass.
What is Mass Number = Protons + Neutrons?
200
This atomic model proposed that electrons travel in fixed, distinct circular orbits (energy levels) around the central nucleus.
What is the Bohr Model?
200
Regardless of the subshell type, this is the maximum number of electrons that any single orbital can hold.

This is the full, standard electron configuration for Nitrogen (Atomic Number 7).
What is 1s² 2s² 2p³?
300
These subatomic particles have a relative charge of -1, almost zero mass (~0 amu), they take up most of the space in an atom.
What are electrons?
300
Listed on the periodic table for each element, this value is the average weight of all naturally occurring isotopes of that element.
What is the AVERAGE atomic mass?
300
This atomic model uses 3D probability maps called atomic orbitals to show where electrons are.
What is the Modern/Quantum Mechanical Model?
300
This spherical subshell contains only 1 orbital and holds up to 2 electrons.
What is the s subshell?
300
This rule states that electrons must fill the lowest energy orbitals available before filling higher energy levels. (German word for building-up)
What is the Aufbau Principle?
400
An atom of Oxygen-17 has this total number of neutrons present in its nucleus.
What are 9 neutrons?
400
Carbon-12 and Carbon-14 differ in weight and stability, but they react identically in chemical reactions because they have the exact same number of these.
What are electrons (or protons)?
NOT NEUTRONS
400
An atomic emission spectrum is produced when an excited electron performs this action, releasing energy in the form of specific wavelengths of light.
What is transitioning/falling back to a lower energy level (or ground state)?
400
How does the physical size of a 1s orbital compare to the size of a 2s or 3s orbital?
What is a 1s orbital is smaller than a 2s or 3s orbital?
400
Found in the last column of the periodic table, these elements naturally have full electron shells and are used to write abbreviated configurations.
What are the Noble Gases?
500
In any neutral atom, these two subatomic particles must always exist in equal numbers.
What are protons and electrons?
500
