This rule states that atoms tend to bond in a way that gives them eight electrons in their outer shell.
What is the Octet Rule?
If heat is released during a chemical reaction, the reaction is classified as this.
What is Exothermic?
This method separates components of a mixture based on their movement through a stationary phase.

What is Filtration?
Used as feedstock in chemical industry, What is the name of the compound C2H6?
What is Ethane?
This term represents the number of protons in an element's nucleus and determines its identity.
What is atomic number?
What is an atom's ability to attract electrons in a chemical bond, which determines the type of bond formed: nonpolar covalent (equal sharing), polar covalent (unequal sharing), or ionic (transfer of electrons).
What is Electronegativity?
A single-step chemical reaction that occurs exactly as written, involving a direct collision of the reactant molecules to form products, with no intermediate steps.
What is Elementary reaction?
This purification method involves dissolving a solid in a hot solvent and then cooling it to form pure crystals.
What is recrystallization?
C₆H₆ is the molecular formula for this aromatic hydrocarbon with a ring structure.
What is Benzene?
A type of chemical reaction that absorbs heat from its surroundings, resulting in a temperature decrease in the surrounding environment.
i.e. Melting of ice
What is endothermic?
This type of bonding occurs when positively charged metal ions are surrounded by a "sea" of delocalized electrons.
What is Metallic Bonding?
A solution with equal concentrations of H⁺ and OH⁻ ions has this pH value.
What is 7 (neutral)?
This technique uses the magnetic properties of carbon to determine the structure of organic molecules.
What is Carbon NMR?
The IUPAC name for CH₃CH₂OH, commonly found in alcoholic beverages.
