This Swedish chemist‘s most famous invention was dynamite, but he is best known for the prestigious international award named after him, that is given annually to people from many fields of study.
Nobel (Alfred)
Given enough information, one can use this to calculate masses, moles, and percents within a chemical equation. (Also one of Mr. S’s favorite words to say)
Stoichiometry
The “special” name for the electrons that exist farthest from an atom’s nucleus.
Valence electrons
The name of the law that relates pressure and volume to a constant number.
Boyle’s law
The ionization energy (the amount of energy needed to take an electron away from an atom) increases as you move both of these directions across the periodic table.
From bottom to top and from left to right.
This English scientist from the 19th century, who was a firm believer in God as the Creator, worked primarily in the study of heat and had a unit of energy named after him in his honor.
Joule (James)
It is beyond the scope of this text (course).
The force per unit area exerted on an object.
Pressure
The standard unit of frequency (1 per second) is named this after a German physicist.
Hertz (Hz)

(May NOT look at the periodic table)
J
The Danish physicist who made foundational contributions to understanding atomic structure and whose model of the atom was based on his idea of specific electron orbits.
Bohr (Niels)
The correct pronunciation of the principle that explains how a chemical reaction will shift in a way that relieves the stress and restores equilibrium.
Le Châtelier’s Principle (luh shat’ tee ayes)
The process by which an atom gains electrons.
