Final answer:
The statement is false; plasma exists as ionized gas with free electrons and positively charged ions, not free neutrons. Plasma is a unique state of matter, abundant in the universe, and distinct from gases.
Step-by-step explanation:
The statement that 'Plasma is the state of matter in which atoms are torn apart and exist as free electrons, atom nuclei, protons, and neutrons' is false. In the plasma state, atoms are ionized, meaning that they are separated into free electrons and positively charged ions (which may include atom nuclei and protons, but not neutrons). Plasma consists of these charged particles moving freely. Plasmas are similar to gases in that the particles are far apart, but they contain a large number of electrically charged particles, thus setting them apart as a distinct state of matter. Plasma is not as common on Earth but is the most abundant form of matter in the universe, being found in the Sun, stars, lightning bolts, and some man-made devices like specialized analytical instruments and certain television screens.
