Drawing Bohr-Rutherford Diagrams for Neutral Atoms

• Remember that for neutral atoms the
• protons electrons
• Look at the atomic number to see how many
  electrons the neutral atom has
• Look at the period number of the element (the
  horizontal row that goes across the periodic
  table)

• The period number tells us how many orbitals or
  shells the electrons are in. Now draw these
  orbitals around the element symbol.
• Remember these values
• 1st shell maximum of 2 electrons
• 2nd shell maximum of 8 electrons
• 3rd shell maximum of 8 electrons
• 4th shell maximum of 18 electrons
