What is hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine, and iodine?
The measurement of Planck's Constant
What is 6.626 * 10 -34, J*S?
The name of the element with the symbol Cu
What is copper?
The scientific notation for milli and micro.
What is 10 -3, m and 10 -6, µ?
The scientist who found where electrons were in an atom and how they moved across energy levels.
Who is Niels Bhor?
The movement patterns of an atom's atomic radius (distance from an atom’s nucleus to the outer edge of the electron cloud) across the periodic table
What increases down a group and decreases across a period, left to right?
The formula used to calculate the wavelength of a wave

The scientific notation for nano and pico.
What is 10 -9, n and 10 -12, p?
The principle that states that electrons occupy the lowest energy levels first, before moving to the next.
What is The Aufbau Principle?
The movement patterns of an atom's ionization energy (the energy required to remove the highest-energy electron from a neutral atom) across the periodic table
What increases across a period and decreases down a group?
The formula used to calculate frequency of a wave
What is v = λ / c?
The name of the element with the symbol K
What is potassium?
This refers to how close measurements of the same item are to each other.
What is Precision?
The principle that states that electrons have to fill all the empty spaces in an orbital first before double occupying them.
What is the Hund's Rule?
The movement patterns of an atom's electronegativity (the measure of the ability of an atom in a bond to attract electrons to itself) across the periodic table
What increases across a period and decreases down a group?
The two formulas used to calculate the energy of a wave
What is E = h*v and E = h*c / λ
The symbol for the element Arsenic
What is As?
This refers to how close a measurement is to the true or accepted value.
