The ELISA method (Enzyme-Linked Immuno-Sorbent Assay) is a technique used in biochemistry to determine if a certain substance–such as a specific cytokine or antigen–is present…

A chemical element is a substance that contains only one type of atom. Elements are the fundamental materials of which all matter is composed. If…

Electroplating is the coating of an object with a metal. It is done by immersing the object and a bar of the metal in a…

Electrolysis is a scientific way of ‘splitting’ substances. It is a way of separating a compound by passing an electric current through it; the products are…

Electrophysiology is the study of the electrical properties of biological cells and tissues. It involves measurements of voltage change or electrical current flow on a…

Electronegativity refers to the ability of an atom to attract shared electrons in a covalent bond. Electronegativity, symbol χ, is a chemical property that says how…

Magnesiopascoite is a bright orange mineral with formula Ca2Mg(V10O28)·16H2O. It formed from post-mining leaching and oxidation of V–U oxide replacements of organic matter. It is…

The valence shell is the outermost shell of every element. It is the outermost shell of an atom in its uncombined state, which contains the…

“Painite” was once considered one of the rarest minerals (borate mineral) on earth. It was first found in Myanmar by British mineralogist and gem dealer…

An electron shell is the outside part of an atom around the atomic nucleus. It is where the electrons are, and is a group of…

Proton decay is a theory where some physicists believe that radioactive decay could also be that a proton decays into two particles smaller than an…

Neutrons, with protons and electrons, make up an atom. They are the particles in an atom that has a neutral charge. Neutrons and protons are found in…
