Presentation Transcript

  1. Read the directions for the lab • Fill in the chemical equation on page 13 • Go the lab area and complete the lab LAB

  2. You should be able to: • Draw and label an element (Level 1-2) • Describe an element and the different parts of an element (Level 3-4) • Identify and describe some patterns in the peiodic table (Level 3-4) • Discuss the organization of the periodic table and how the patterns shaped the organization of the periodic table (Level 5-6) Your Goals

  3. http://www.youtube.com/watch?v=ssaUusY6hWM (the elements song) • A million atoms would fit on the head of a pin. • Atoms are made of mostly empty space • If an atom were magnified to the size of a football stadium, the nucleus of the atom would be the size of a pea in the center of the stadium, and the electrons would be whizzing around the outer stands. Tour of the Elements & the Periodic Table http://www.bbc.co.uk/news/science-environment-22364761 http://www.youtube.com/watch?v=v1TfPDlA1xE (Daniel Radcliffe)

  4. Dmitri Mendeleev • 1834-1907 • Russian chemist • 60 known elements • Predicted new elements: • Boron, silicon, & aluminum Periodic Table: then & now

  5. An atom with a specific number of protons in the nucleus. Phosphorous Sulfur Silicon What is an Element? 1669 HennigBrand  German Alchemist Phosphorous from urine Glows with oxygen

  6. 3 protons = atomic number Nucleus Number or protons = number of neutrons = number of electrons • Draw Lithium • Find the atomic number – draw & label the nucleus: protons & neutrons • Find the period number – draw the shells • Add in the electrons and label • Electron Shell maximums:2 – 8 – 8 – 18 – 18 – 32

  7. Draw potassium (page 12)
