Electrochemistry. English chemist John Daniell (left) and physicist Michael Faraday (right), both credited as founders of electrochemistry. Electrochemistry is the branch of physical chemistry concerned with the relationship between electrical potential difference and identifiable chemical change. These reactions involve electrons moving via an ...
Reducing agent. In chemistry, a reducing agent (also known as a reductant, reducer, or electron donor) is a chemical species that "donates" an electron to an electron recipient (called the oxidizing agent, oxidant, oxidizer, or electron acceptor ). Examples of substances that are common reducing agents include hydrogen, the alkali metals ...
Ionization (or ionisation specifically in Britain, Ireland, Australia and New Zealand) is the process by which an atom or a molecule acquires a negative or positive charge by gaining or losing electrons, often in conjunction with other chemical changes. The resulting electrically charged atom or molecule is called an ion.
In aqueous solutions, redox potential is a measure of the tendency of the solution to either gain or lose electrons in a reaction. A solution with a higher (more positive) reduction potential than some other molecule will have a tendency to gain electrons from this molecule (i.e. to be reduced by oxidizing this other molecule) and a solution with a lower (more negative) reduction potential ...
Redox ( / ˈrɛdɒks / RED-oks, / ˈriːdɒks / REE-doks, reduction–oxidation [2] or oxidation–reduction [3] : 150 ) is a type of chemical reaction in which the oxidation states of the reactants change. [4] Oxidation is the loss of electrons or an increase in the oxidation state, while reduction is the gain of electrons or a decrease in the ...
The blog Minimalist Baker features recipes that use 10 ingredients or less and only take about 30 minutes to make. The site also has a wealth of vegetarian recipes to experiment with, like this ...
Electron excitation. Electron excitation is the transfer of a bound electron to a more energetic, but still bound state. This can be done by photoexcitation (PE), where the electron absorbs a photon and gains all its energy [ 1] or by collisional excitation (CE), where the electron receives energy from a collision with another, energetic ...
In chemistry, delocalized electrons are electrons in a molecule, ion or solid metal that are not associated with a single atom or a covalent bond. [ 1] The term delocalization is general and can have slightly different meanings in different fields: In organic chemistry, it refers to resonance in conjugated systems and aromatic compounds.
