Definition: All substance are made up of Particles (basic units) that are in constant motion (therefore has energy) and sometimes they interact.

*There are two different ways that particles can interact:
**1) The components that make up the Particles can regroup to create new grouping (I call new Particles). We call this a Chemical Reaction (chemical change). Chemical reaction are based on Collision Theory at your level of understanding.

*By the way, Feynman, really really smart dude.

There are four (4) basic principles that can be used to describes all chemical concepts. To explain a concept, one can utilize one or more of these principle.

Kinetic Molecular Theory (KMT)
Definition: All substance are made up of Particles (basic units) that are in constant motion (therefore has energy) and sometimes they interact/collide.

There are two different ways that particles can interact/collide:
- 1) The components that make up the Particles can regroup to create new grouping (I call new Particles). We call this a Chemical Reaction (chemical change). Chemical reaction are based on Collision Theory at your level of understanding. The forces that are overcome to create the regrouping are called Intramolecular Force.
- 2) The components that make up the Particles DO NOT REGROUP so that Particles do not change but they just influence each other. We call this a Physical process. The influnece is called Intermolecular Force (IMF)
College Board AP chemistry does not use the name KMT but inside uses the phrase "particle view of matter". This means the same thing as KMT.

Conservation of Mass
Definition: Mass can not be gained nor lost in a physical process or chemical reaction. A more simple def is Mass is conserved.

In general chemistry (excluding nuclear chemistry), we do not use Einstein equation, E=mc² which basically means that Energy (E) can be changed directly into matter (m). Not in our chemistry.

Conservation of Energy
Definition: See above Conservation of Matter definition and replace mass with energy (including Einstein work)

Coulombic Force (those are my words, real name is Coulomb Law)
Definition: Same charge particles repel, different charge particles attract.

If you are having a hard time understanding it, it is like when magnets interact
Feynman said that if all human knowledge was eliminated and you need one concept to figure out all other concepts, it would be Coulomb Law.
