Most Popular
Electrochemistry
Study of chemical changes produced by electrical current and the production of electricity by chemical reactions.
Hydrogenation
The reaction in which hydrogen adds across a double or triple bond.
Mother Nuclide
Nuclide that undergoes nuclear decay.
Oxidation
An algebraic increase in the oxidation number, may correspond to a loss of electrons.
Thermonuclear Energy
The energy stored in the nucleus of an atom and released through fission, fusion, or radioactivity. In these processes a small amount of mass is converted to energy according to the relationship E = mc2, where E is energy, m is mass, and c is the speed of light.
Alkaline Earth Metals
Group IIA metals
Native State
Refers to the occurrence of an element in an uncombined or free state in nature.
Weak Electrolyte
A substance that conducts electricity poorly in a dilute aqueous solution.
Chain Reaction
A reaction that, once initiated, sustains itself and expands. This is a reaction in which reactive species, such as radicals, are produced in more than one step. These reactive species, radicals, propagate the chain reaction.
Electrophile
Positively charged or electron-deficient.
