4
Smallest unit of an element that keeps the properties of that element If broken apart; no longer that element.
5
A pure substance, One type of atom Cannot be broken down into simpler substances by chemical means
6
Each element has a UNIQUE amount of PROTONS. Protons and Neutrons exist together in the ___________________ of the atom. Surrounding the nucleus, is the electron cloud are the negatively charged particles called _______________. Nucleus Electrons
7
1. Electron Configurations can be seen through the Bohr Model or by using Wave Mechanics. 2.For the simpler atoms we will be using the Bohr Model.
8
1.From the Periodic Table, we can draw the Bohr Model showing the contents of the nucleus and the # of shells with electrons. P=1 N=0 2
