Bohr Model
  • The Bohr Model shows all of the particles in the atom.
  • In the center is circles. Each circle represents a single neutron or proton. Protons should have a plus or P written on them. Neutrons should be blank or have an N.
  • In a circle around the nucleus are the electrons. Electrons should have a minus sign or an e.
slide5

You can’t just shove all of the electrons into the first orbit of an electron.

  • Electrons live in something called shells or energy levels.
  • Only so many can be in any certain shell.
  • The electrons in the outer most shell of any element are called valance electrons.
try an example
Try an Example!
  • How to draw a Lithium atom
  • First, look at the Periodic Table
  • Second, determine the number of protons (Look @ the atomic number)
  • Then determine the number of neutrons (Atomic mass – atomic number)
  • Then determine the number of electrons (Look @ the atomic number)

Lewis Dot Diagrams
  • The Lewis Dot Structure is a bit different from the Bohr model.
  • It only shows the element symbol and it’s outer most electron shell.
slide13

Step 1: Write the Element Symbol

  • Step 2: Find the number of electrons in the last energy level of the Bohr Model (Valence Electrons)
  • Step 3: Place the electrons (dots) around the symbol in clockwise order so that there are no more than 2 electrons per side.
