First of all, let us
get one thing straight: plasma is not a rare, mysterious
substance that is in between the liquid state of matter
and the solid state. It is estimated that 99% of our
entire universe is made of plasma. It is only rare here on
Earth because the conditions to make plasma are so
extreme. It is the state of matter that comes after the
gaseous state of matter. In Chemistry, authors
Raymond Chang and Ken Goldsby describe plasma as "... a
gaseous mixture of positive ions and electrons..."
(www.plasmas.org/what-are-plasmas.htm)
Plasma is special in that it
exhibits properties of gas, such as not having shape
or volume unless confined in a container and having
very large distances between particles, but is also an
excellent conductor because of all those free
electrons (unlike gases; gases are notoriously poor
conductors), and also can be directed by a magnetic field.
However, the question is, how did those electrons
become so footloose and fancy free? Aren't electrons
and the nucleus of an atom bonded together tightly?
The answer lies in the next page.
