3b) Conservation of Energy - In a physical process and/or chemical reaction, energy is neither created nor destroyed (i.e. has to be conserved/accounted for). Also called First Law of Thermodynamics
4) Coulomb's Law ( I called it Coulombic Force, CF).
5) When particles collide, they can either
a) stay same - called physical change or
b) reorganize/rearrange - called chemical change (also called chemical reaction).
6)
7) Less energy but higher CF to nucleus (conversely an electron in a higher energy level, further away from nucleus, has more energy but has a lower CF to nucleus)
8) Release/give off valence electron (ve-) (because these ve- tend to be in higher energy level so less CF to nucleus).
9) Keep or gain ve- (because these ve- tend to be in lower energy levels so more CF to nucleus).
10) Intramolecular forces are forces that hold the "particle together" whereas Intermolecular forces are between particles (for molecules only now). There are three Intramolecular forces:
a) Metallic bond is when two or more metal elements get close to each other.
b) "Ionic bond" is when a metal and non-metal elements get close to each other.
c) Covalent bond is when two non-metal elements (can have more than 2) get close to each other.

14)Distribution of electrons. Unevenly distributed electrons cause polar molecules whereas "overall/on average" distributed electrons cause non-polar molecules.
15) Activation energy (Eac)is the minimum amount of energy for a set of reactants to form a set of products.
16) Besides Activation energy (Eac), the particles must be in the spacial orientation (close enough to collide and in correct 3-D location compared to other reacting particles). Of course, Effective collision (EC) of reactants cause products to be made.
