Document Summary
Matter is made up of atoms and molecules; meaning anything made of positively charged protons, neutral neutrons, and negatively charged electrons. Gravitational force: also known as gravity, which makes any two objects, and particle, attract. It has an in nite range and its e ects become exponentially weaker as distance increases. Electromagnetic: compared to gravity its a much stronger force. One major di erence is that it acts only between charged particles pulling or pushing them apart, depending on their charge. Strong nuclear: it is by far the strongest force known in the universe (wow). It can be observed holding protons and neutrons together in atoms. Weak nuclear: weaker than electromagnetic though much stronger than gravitational force. An atom is a form of matter which may not be further broken down. A typical atom consists of protons, neutrons, and electrons. Development of the fundamental chemical laws and the atomic theory:
