States of Matter

1. SOLID - atoms are generally highly organized; very low atomic speeds; retains a fixed shape.
   
2. LIQUID - atoms are less organized; low atomic speeds; conforms to shape of a container.
   
3. GAS - atoms are disorganized; high atomic speeds; fills a volume
   
4. PLASMA - contains ionized particles, electrons, AND neutral atoms; high atomic speeds; fills a volume; can be confined by electric and magnetic fields
