Document Summary

How do we differentiate living from non-living : complexity with precise spatial organization, ability to respond to the environment, reproduction, evolve- non living systems do not evolve over time.

The atom is the fundamental unit of matter: element is composed of an atom, atom is a dense central nucleus made up of positive and electrically charge particles (neutrons, negatively charged electrons move around the nucleus. Atoms can combine to form molecules linked by chemical bonds.
