Transcript of "How to draw bohr diagrams (slideshare)"

  1. 1. How to DrawBohr Diagrams
  2. 2. Atomic Structure• Atoms have a nucleus that contains Protons and Neutrons• Electrons are contained in shells that surround the nucleus• An atom is made of mostly empty space• Protons have a positive (+) charge• Electrons have a negative (-) charge• Neutrons are Neutral
  3. 3. Valence Electrons• Each electron shell can hold Electron Number of a certain number of Shell Electrons electrons• Electron shells are filled 1 2 from the inside out 2 8• Noble Gases have full outer 3 8 electron shells• All other elements have 4 18 partially filled outer 5 18 electron shells 6 32 7 32
  4. 4. Valence Electrons• The electrons in the outer most electron shell are called valence electrons• The shell containing electrons that is furthest from the nucleus is called the valence shell• The number of electron shells with electrons is the same as (=) the period number• Atoms will try to gain or lose electrons to have a full valence shell
  5. 5. Bohr Diagrams1) Find your element on the periodic table.2) Determine the number of electrons – it is the same as the atomic number.3) This is how many electrons you will draw.
  6. 6. Bohr Diagrams • Find out which period (row) your element is in. • Elements in the 1st period have one energy level. • Elements in the 2nd period have two energy levels, and so on.
  7. 7. Bohr Diagrams 1) Draw a nucleus with the element symbol inside. 2) Carbon is in the 2ndC period, so it has two energy levels, or shells. 3) Draw the shells around the nucleus.
  8. 8. Bohr Diagrams 1) Add the electrons. 2) Carbon has 6 electrons.C 3) The first shell can only hold 2 electrons.
  9. 9. Bohr Diagrams 1) Since you have 2 electrons already drawn, you need to add 4 more.C 2) These go in the 2nd shell. 3) Add one at a time -starting on the right side and going counter clock-wise.
  10. 10. Bohr Diagrams • Check your work. • You should have 6 total electrons for Carbon. • Only two electrons canC fit in the 1st shell. • The 2nd shell can hold up to 8 electrons. • The 3rd shell can hold 18, but the elements in the first few periods only use 8 electrons.
  11. 11. Bohr Diagrams End of Study Guide.You should know how to draw a Bohr Diagram for the first 20 elements.
