In physics, a charged particle is a particle with an electric charge. It may be either a subatomic particle or an ion. A collection of charged particles, or even a gas containing a proportion of charged particles, is called a plasma, which is called the fourth state of matter because its properties are quite different from solids, liquids and gases (plasma is the most common state of matter in the universe). Particles either have a positive, negative or no charge (being neutral).
Their effects go beyond the laboratory (see aurora borealis).
Famous quotes containing the words charged and/or particle:
“I am trembling:
I am suddenly charged with their language, these six strings,
Suddenly made to see they can declare
Nothing but harmony, and may not move
Without a happy stirring of the air
That builds within this room a second room....”
—Philip Larkin (1922–1986)
“The way to learn German, is, to read the same dozen pages over and over a hundred times, till you know every word and particle in them, and can pronounce and repeat them by heart.”
—Ralph Waldo Emerson (1803–1882)
