Do now
DO NOW

  • 1. What element has the chemical symbol K?

  • 2. How many neutrons does Hydrogen have?

  • 3. How many electrons are in the outer orbit level of aluminum? (need to make a Bohr model)


GOAL

  • To construct Bohr models

  • To use the periodic table and become familiar with its elements

Describe the locations of the elements
Describe the locations of the elements

  • Ex: Neon is a non-metal located in period 2, gp 18 (noble gases)

  • Sodium

  • A metal located in period 3, gp 1, the

  • Nickel

  • A transition metal located in period 4, gp 10

  • Fluorine

  • A non-metal in period 2, grp 17 (halogens)
