Atoms are the primary building blocks of ordinary matter, and they come in many different varieties, known as elements. Use ChemistHunter.com to explore the elements of the periodic table. Learn about the different groups of elements, from alkali metals to noble gases.

Chemical compounds are the building blocks of matter. From the air we breathe to the ground beneath our feet to the processes of life, everything depends on the underlying chemical species. Chemist Hunter has information such as chemical structure, molecular formula, molar mass and much more for a vast array of different chemical compounds.

Ions are charged chemical species, which can be either a single atom, called monatomic ions, or many atoms held together by covalent bonds, called polyatomic ions. Use ChemistHunter.com to find information on ions and classes of ions.

Correct handling of quantities and units is of paramount importance for the working chemist. Use ChemistHunter.com to compute extensive properties for chemicals, which depend on the amount of substance present, and to convert quantities between different units.

A solution is one type of homogeneous mixture. Solvation occurs when solution components have similar stabilizing interactions. Two substances are miscible if they can solvate each other at any concentration. The physical and chemical properties of all components change upon dissolution. ChemistHunter.com has extensive solubility knowledge of various compounds in both polar and nonpolar solvents.

Chemical reactions, the transformation from one molecular structure to another, are ubiquitous in the world around us. Everything from internal combustion engines and complex manufacturing plants to geological processes and life itself depend on chemical reactions. Use ChemistHunter.com to balance chemical equations, determine reaction stoichiometry and predict products.

Chemical thermodynamics describes the physical changes of state within the limits placed by the laws of thermodynamics. ChemistHunter.com provides thermodynamics equations and computations to determine a variety of chemical properties such as pressure, boiling point and speed of sound for many chemicals and compounds.

A functional group is a group of atoms within a molecule with distinctive properties largely independent of the rest of the molecule. From acidic carboxyl groups to basic amine groups, functional groups determine the reactivity of their parent compounds. With ChemistHunter.com, you can explore functional groups such as cyanates, peroxides, alkanes and halides.

Cheminformatics (also known as chemoinformatics or chemioinformatics) is a subfield of computational chemistry, utilizing chemical topology, graph theory and data mining for purposes such as drug discovery and substructure filtering. Use ChemistHunter.com to explore cheminformatics properties, from graph invariants like Balaban's J-index or the Hosoya index to QSAR descriptors like the hydrogen donor count and longest chain.

Quantum chemistry is the application of quantum mechanics to chemical problems. With ChemistHunter.com, one can investigate the connection between observed chemical properties and the underlying quantum mechanical nature of atoms and molecules. Explore properties such as electronic configurations, orbital diagrams, term symbols and emission spectra.

Atoms are held together in molecules by chemical bonds. Electrons occupy bonding, antibonding or nonbonding molecular orbitals that can be classified as sigma-, pi-, delta- or phi-like. The number of electrons in bonding and antibonding orbitals between a pair of atoms gives rise to the bond order for those atoms with values ranging from one to six. Use ChemistHunter.com to find out about the different types of bonds in molecules and to compute the orbital hybridization.

Nuclear chemistry is the study of chemical reactions involving changes in the number of protons and neutrons within each atom. With ChemistHunter.com, one can explore the nuclear structure and properties of nuclides, such as the symbols, mass and neutron numbers, mass defects, binding energies and cosmic origins.
