Ion
An ion is an atom or molecule in which the total number of electrons is not equal to the total number of protons, giving it a net positive or negative electrical charge. The name was given by physicist Michael Faraday for the substances that allow a current to pass ("go") between electrodes in a solution, when an electric field is applied. It is from Greek ιον, meaning "going".
An ion consisting of a single atom is an atomic or monatomic ion; if it consists of two or more atoms, it is a molecular or polyatomic ion.

Iodate refuses to intimidate
Like a bull in a china shop, a massive, iodine-based ion called iodate should disrupt the surrounding water molecules until it is forcibly expelled. However, it doesn't. This disconnect between the molecule's ...

Computer simulations give insights into how carbon dioxide reacts with a sequestering liquid
(PhysOrg.com) -- Worse than toddlers on a sugar high, carbon dioxide molecules just don't like standing still. The tiny molecules, just three atoms, leap from place to place in less than a trillionth of a ...

New research reveals how alpha-synuclein interacts with cell membranes in Parkinson's disease
The accumulation of α-synuclein, a small, negatively charged protein, in neural cells, is one of the hallmarks of Parkinson's disease. It has been suggested that oligomeric α-synuclein causes membranes to become ...
