Nykoya Watson Chemistry September 2, 2010 Lecture 2 Dominant truisms of our world The first dominant truism : o Systems attempt to go to low energy, if a pathway exists and if enough energy is present to allow the system to get to low energy. A second dominant truism is that: o Two objects cannot occupy the same space at the same time. A third dominant truism is that: o Objects and particles can have no electrical charge or either positive or negative charge. A fourth dominant truism is that: o Positive and negative charges attract each other. o Whereas like charges repel each other. The Bohr Model of the Atom A simple model of an atom, which take into account the dominant truisms: o Atoms consist of a positively charged nucleus and negatively charge electrons. A normal atom at low energy (stable) has an equal number of electrons to the charge of the nucleus. The nuclear charge comes from protons in nucleus. The smallest atom, hydrogen, has one proton and one electron. Atoms can exist in more than one state. Extra slide goes here
