2. Smallest unit of an element that keeps the properties of that element If broken apart; no longer that element.

3. A pure substance, One type of atom Cannot be broken down into simpler substances by chemical means

4. 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

5. 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.

6. 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

12. Two or more atoms bonded (chemical forces) Form compounds Smallest unit of any compound that keeps the properties of that compound.

13. A pure substance A substance made up of atoms from two or more different elements bonded.

14. A combination of two or more substances blended together No set ratio of ingredients

15. Homogeneous: 2 or more things evenly blended and disappear into each other. Solute – Smaller quantity Solvent – Larger quantity Solution – a homogeneous mixture
