Chemical formulas

Aromaticity

In organic chemistry, aromaticity is a chemical property describing the way in which a conjugated ring of unsaturated bonds, lone pairs, or empty orbitals exhibits a stabilization stronger than would be expected by the stabilization of conjugation alone.

See Lewis structure and Aromaticity

Arrow pushing or electron pushing is a technique used to describe the progression of organic chemistry reaction mechanisms.

See Lewis structure and Arrow pushing

Atom

Atoms are the basic particles of the chemical elements.

Chemical bond

A chemical bond is the association of atoms or ions to form molecules, crystals, and other structures. Lewis structure and chemical bond are chemical bonding.

See Lewis structure and Chemical bond

Chemical polarity

In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole moment, with a negatively charged end and a positively charged end.

See Lewis structure and Chemical polarity

Coordination complex

A coordination complex is a chemical compound consisting of a central atom or ion, which is usually metallic and is called the coordination centre, and a surrounding array of bound molecules or ions, that are in turn known as ligands or complexing agents.

Electron

The electron (or in nuclear reactions) is a subatomic particle with a negative one elementary electric charge.

See Lewis structure and Electron

Formal charge

In chemistry, a formal charge (F.C. or), in the covalent view of chemical bonding, is the hypothetical charge assigned to an atom in a molecule, assuming that electrons in all chemical bonds are shared equally between atoms, regardless of relative electronegativity. Lewis structure and formal charge are chemical bonding.

See Lewis structure and Formal charge

Gilbert N. Lewis

Gilbert Newton Lewis (October 23 or October 25, 1875 – March 23, 1946) was an American physical chemist and a dean of the college of chemistry at University of California, Berkeley.

Journal of Chemical Education

The Journal of Chemical Education is a monthly peer-reviewed academic journal available in both print and electronic versions.

See Lewis structure and Journal of Chemical Education

Lone pair

In chemistry, a lone pair refers to a pair of valence electrons that are not shared with another atom in a covalent bondIUPAC Gold Book definition: and is sometimes called an unshared pair or non-bonding pair. Lewis structure and lone pair are chemical bonding.

See Lewis structure and Lone pair

Main-group element

In chemistry and atomic physics, the main group is the group of elements (sometimes called the representative elements) whose lightest members are represented by helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, and fluorine as arranged in the periodic table of the elements.

See Lewis structure and Main-group element

Molecular geometry

Molecular geometry is the three-dimensional arrangement of the atoms that constitute a molecule.

See Lewis structure and Molecular geometry

Molecular orbital

In chemistry, a molecular orbital is a mathematical function describing the location and wave-like behavior of an electron in a molecule. Lewis structure and molecular orbital are chemical bonding.

See Lewis structure and Molecular orbital

Molecular orbital theory

In chemistry, molecular orbital theory (MO theory or MOT) is a method for describing the electronic structure of molecules using quantum mechanics. Lewis structure and molecular orbital theory are chemical bonding.

See Lewis structure and Molecular orbital theory

Molecule

A molecule is a group of two or more atoms held together by attractive forces known as chemical bonds; depending on context, the term may or may not include ions which satisfy this criterion.

See Lewis structure and Molecule

Natural bond orbital

In quantum chemistry, a natural bond orbital or NBO is a calculated bonding orbital with maximum electron density.

See Lewis structure and Natural bond orbital

Nitrite

The nitrite ion has the chemical formula.

See Lewis structure and Nitrite

Octet rule

The octet rule is a chemical rule of thumb that reflects the theory that main-group elements tend to bond in such a way that each atom has eight electrons in its valence shell, giving it the same electronic configuration as a noble gas. Lewis structure and octet rule are chemical bonding.

Organic chemistry

Organic chemistry is a subdiscipline within chemistry involving the scientific study of the structure, properties, and reactions of organic compounds and organic materials, i.e., matter in its various forms that contain carbon atoms.

See Lewis structure and Organic chemistry

Organic compound

Some chemical authorities define an organic compound as a chemical compound that contains a carbon–hydrogen or carbon–carbon bond; others consider an organic compound to be any chemical compound that contains carbon.

See Lewis structure and Organic compound

Organometallic chemistry is the study of organometallic compounds, chemical compounds containing at least one chemical bond between a carbon atom of an organic molecule and a metal, including alkali, alkaline earth, and transition metals, and sometimes broadened to include metalloids like boron, silicon, and selenium, as well.

Partial charge

In atomic physics, a partial charge (or net atomic charge) is a non-integer charge value when measured in elementary charge units.

See Lewis structure and Partial charge

Period 2 element

A period 2 element is one of the chemical elements in the second row (or period) of the periodic table of the chemical elements.

Reaction mechanism

In chemistry, a reaction mechanism is the step by step sequence of elementary reactions by which overall chemical reaction occurs.

See Lewis structure and Reaction mechanism

Resonance (chemistry)

In chemistry, resonance, also called mesomerism, is a way of describing bonding in certain molecules or polyatomic ions by the combination of several contributing structures (or forms, also variously known as resonance structures or canonical structures) into a resonance hybrid (or hybrid structure) in valence bond theory. Lewis structure and resonance (chemistry) are chemical bonding.

Skeletal formula

The skeletal formula, line-angle formula, bond-line formula or shorthand formula of an organic compound is a type of molecular structural formula that serves as a shorthand representation of a molecule's bonding and some details of its molecular geometry. Lewis structure and skeletal formula are chemical formulas.

See Lewis structure and Skeletal formula

Space-filling model

In chemistry, a space-filling model, also known as a calotte model, is a type of three-dimensional (3D) molecular model where the atoms are represented by spheres whose radii are proportional to the radii of the atoms and whose center-to-center distances are proportional to the distances between the atomic nuclei, all in the same scale.

See Lewis structure and Space-filling model

Structural formula

The structural formula of a chemical compound is a graphic representation of the molecular structure (determined by structural chemistry methods), showing how the atoms are possibly arranged in the real three-dimensional space. Lewis structure and structural formula are chemical formulas.

Topology

Topology (from the Greek words, and) is the branch of mathematics concerned with the properties of a geometric object that are preserved under continuous deformations, such as stretching, twisting, crumpling, and bending; that is, without closing holes, opening holes, tearing, gluing, or passing through itself.

See Lewis structure and Topology

Valence electron

In chemistry and physics, valence electrons are electrons in the outermost shell of an atom, and that can participate in the formation of a chemical bond if the outermost shell is not closed. Lewis structure and valence electron are chemical bonding.
