How is plasma formed?
A plasma is created when one or more electrons are torn free from an atom. … A plasma is generally a mix of these positively charged ions and negatively charged electrons. Most plasmas are created when extra energy is added to a gas knocking electrons free from atoms. High temperatures often cause plasmas to form.
