Study Notes

Inorganic Chemistry: Study of inorganic compounds, such as minerals and salts.
Organic Chemistry: Study of organic compounds, such as hydrocarbons and their derivatives.
Physical Chemistry: Study of the physical properties and behavior of matter at the molecular and atomic level.
Analytical Chemistry: Study of the analysis and identification of the chemical composition of substances.
Biochemistry: Study of the chemical processes that occur within living organisms.

Proton: Positively charged subatomic particle in the nucleus of an atom.
Neutron: Neutral subatomic particle in the nucleus of an atom.
Electron: Negatively charged subatomic particle that orbits the nucleus of an atom.
Atomic Number: Number of protons in the nucleus of an atom, which determines the element.
Atomic Mass: Total number of protons and neutrons in the nucleus of an atom.

Covalent Bond: Chemical bond formed by sharing electrons between atoms.
Ionic Bond: Chemical bond formed by the transfer of electrons between atoms.
Polar Covalent Bond: Chemical bond formed by unequal sharing of electrons between atoms.

Chemical Equation: Symbolic representation of a chemical reaction, with reactants on the left and products on the right.
Reactants: Substances that undergo a chemical change in a reaction.
Products: Substances formed as a result of a chemical reaction.
Catalyst: Substance that speeds up a chemical reaction without being consumed.

Acid: Substance that donates a proton (H+ ion).
Base: Substance that accepts a proton (H+ ion).
pH: Measure of the concentration of hydrogen ions in a solution, with a pH of 7 being neutral.

Mole: Unit of measurement for the amount of a substance, defined as 6.022 x 10^23 particles.
Molar Mass: Mass of one mole of a substance, typically measured in grams per mole (g/mol).
Stoichiometric Coefficient: Number that indicates the relative amount of a reactant or product in a chemical equation.
