  1. Structure of the atom Section 17.1

  2. Warm up • What is the building block of matter? • What do you think these building blocks are made up of?

  3. Objectives • Identify the names and symbols of common elements. • Identify the subatomic particles. • Describe the electron cloud model of the atom. • Explain how electrons are arranged in an atom

  4. Introduction • Do you have a nickname? • What is your nickname. • What does each of the following mean? 1- BTW 2- BRB 3- IDK 4- LOL

  5. Scientific Shorthand • Scientists have developed their own shorthand for dealing with long complicated names. • What is a chemical symbol?

  6. Atomic components • Do you recall what is an element? • Atoms are composed of a central part, the nucleus, that is surrounded by a cloud of electrons.

  7. Protons, neutrons, electrons and quarks

  8. Visualizing the atomic model
