Brown v. Board of Education

A landmark Supreme Court case declaring that racial segregation in public schools is unconstitutional.

Inorganic Chemistry

The study of inorganic compounds, typically those that do not contain carbon-hydrogen bonds.

S-block

Elements in the first two groups of the periodic table, which include the alkali metals and alkaline earth metals.

P-block

The section of the periodic table containing groups 13 to 18, which includes metals, nonmetals, and metalloids.

D-block

Elements that are transition metals, found in groups 3 to 12 of the periodic table.

Electron Configuration

The distribution of electrons among the various orbitals of an atom.

Metalloid

Elements that have properties intermediate between metals and nonmetals.

Acid-Base Reaction

A reaction between an acid and a base producing salt and water.

Oxidation State

The charge of an atom in a molecule or ionic compound.

Hydrogen Bonding

A type of attractive interaction between a hydrogen atom, which is covalently bonded to an electronegative atom, and another electronegative atom.

Amphoteric Substance

A chemical species that can act as both an acid and a base.

Dative Bonding

A type of coordinate bond where one atom donates both electrons to shared bonding.

Hybridization

The mixing of atomic orbitals to form new hybrid orbitals suitable for the pairing of electrons.

Valence Electrons

Electrons in the outermost shell of an atom that are involved in chemical bonding.

Boric Acid

A weak acid that is often used as an antiseptic or insecticide, formulated as H3BO3.

Pyrophoric Substance

A substance that ignites spontaneously in air at or below room temperature.

Coordinated Compound

A complex that consists of a central atom bonded to surrounding molecules or ions, known as ligands.

Allotropes

Different forms of the same element in the same physical state.

Atomic Radius

The distance from the nucleus of an atom to the outermost shell of electrons.

Electronegativity

A measure of the tendency of an atom to attract a bonding pair of electrons.

Coordination Number

The number of ligand donor atoms that are bonded to the central metal atom in a complex.

Geometric Isomers

Compounds that have the same molecular formula but differ in the arrangement of atoms in space.

Flexible Polymers

Polymers that exhibit the ability to be molded or shaped and that may also have varying mechanical properties.

Thermal Stability

The ability of a chemical substance to maintain its physical and chemical properties at high temperatures.

Hydrolysis

The reaction of a substance with water, leading to its breakdown or change.

Nucleophile

A chemical species that donates an electron pair to form a chemical bond.

Alkali Metal

Elements in group 1 of the periodic table, known for being highly reactive, especially with water.

Transition Metal

Elements that have a partially filled d-subshell and exhibit variable oxidation states.

Crystal Lattice

A three-dimensional arrangement of atoms, ions, or molecules in a crystalline solid.

Molecular Orbital Theory

A theory that accounts for the properties of molecules in terms of molecular orbitals that are formed by the combination of atomic orbitals.
