The topics are Boiler, Carpet, Chemistry, Corrosion, Electric Power, Energy, Environment, Environmental Toxins, Huntingtons Disease, Nuclear, Nuclear Science, Physical Geography, Plumbing, Prostate Cancer, Pyrotechnics, Robotics, Sanitation, Science, Solar Energy and Solar Physics.

A charged atom or radical which may be positive or negative.
See more Boiler Terms ...

A molecule sized particle tht has either a positive or negtive charge.
See more Carpet Terms ...

An atom with an electric charge due to gain or loss of electrons.
See more Chemistry Terms ...

An atom, or group of atoms, that has gained or lost one or more outer electrons and thus carries an electric charge. Positive ions, or cations, are deficient in outer electrons. Negative ions, or anions, have an excess of outer electrons
See more Corrosion Terms ...

An atom that is electrically-charged because of loss or gain of electrons.
See more Electric Power Terms ...

An atom or group of atoms that is electrically charged.
See more Energy Terms ...

An electrically charged atom or group of atoms.
See more Environment Terms ...

Atomic particle, atom or chemical radical bearing an electric charge, either negative or positive.
See more Environmental Toxins Terms ...

An atom or group of atoms that carries a positive or negative electric charge as a result of having lost or gained one or more electrons (negatively-charged particles). An example of an ion is Na+ (a sodium atom that has become positively charged by losing an electron).
See more Huntingtons Disease Terms ...

An atom that is electrically charged because of loss or gain of electrons.
See more Nuclear Terms ...

An atomic particle that is electrically charged, either negative or positive.
See more Nuclear Science Terms ...

An atom, molecule or compound that carries either a positive (cation) or negative (anion) electrical charge.
See more Physical Geography Terms ...

An atom or group of atoms which function as a unit, and have a positive (cation) or negative (anion) electrical charge, due to the gain or loss of one or more electrons.
See more Plumbing Terms ...

Atom or molecule that has acquired an electric charge by the loss or gain of one or more electrons
See more Prostate Cancer Terms ...

An atom with a larger/smaller than normal number of electrons, resulting in an overall negative or positive charge, respectively
See more Pyrotechnics Terms ...

An atom with a different number of electrons than protons. An ion will therefore have a net electric charge.
See more Robotics Terms ...

A charged atom or radical, the migration of which affects the transport of electricity through an electrolyte or, to a certain extent, through a gas. An atom or molecule that has lost or gained one or more electrons.
See more Sanitation Terms ...

An atom or molecule that has become electrically charged through the loss or gain of one or more electrons.
See more Science Terms ...

An electrically charged atom or group of atoms that has lost or gained electrons; a loss makes the resulting particle positively charged; a gain makes the particle negatively charged.
See more Solar Energy Terms ...

An atom that has lost or gained one or more electrons and has become electrically charged as a result.
See more Solar Physics Terms ...
