What is an atom made of? An atom is defined as the smallest particle of an element, and it retains the properties of the element. We already know that.

Section III: A World of Particles Lesson 11 Atomic Pudding Lesson 12 Atoms By Numbers Lesson 13 Subatomic Heavyweights Lesson 14 Isotopia Lesson 15 Nuclear Quest Lesson 16 Old Gold

Lesson 11: Atomic Pudding Models of the Atom (start on a new RIGHT side and add to table of contents)

Key Question (right side) How are the smallest bits of matter described? Objectives: describe the development of the current atomic model describe and draw an atomic model

Lesson 11 notes: (right side) Atom: The smallest unit of an element that retains the chemical properties of that element.

Notes (cont.) Do not copy The Atomic Model Through Time

Notes (cont.) a.) Models of the atom changed as new evidence was gathered Current Model of the atom: Know this!!

Notes (cont.) b.) Parts of an atom Nucleus: Center of atom Contains protons and neutrons VERY small, very dense Proton: Positive (+) charge Found in nucleus Neutron: NO charge or neutral (0)

Notes (cont.) Electron: Negative charge (-) Smallest particle Move very fast around the outside of the nucleus

Check-in 11 Here is a model of a carbon atom. 1. List two things this model tells you about the carbon atom. 2. List something this model does not tell you about the carbon atom.
