Lesson 04 ­ Bohr­Rutherford Diagrams.notebook February 07, 2013 Yesterday's Ticket out of class 1 Lesson 04 ­ Bohr­Rutherford Diagrams.notebook February 07, 2013 Date: ____________________ Bohr­Rutherford Diagrams One way to represent an element that can be very useful is to use diagrams. Bohr­Rutherford Diagrams show the number of _________________ and __________________ in the nucleus and the number of _________________ that orbit that nucleus for each element. Bohr­ Rutherford Diagrams get their name from two scientists who contributed to our current model of the atom. protons neutrons electrons Rutherford Rutherford conducted experiments and found that the nucleus contained all positive of the _________________ charge in the atom. He found this out by shooting positive alpha particles at gold foil ________________________. When some of the particles _____________________ back he knew that the part of the atom they had bounced positive hit must be ______________________ causing them to repel. negative negative Bohr Bohr built upon Rutherford's ideas by conducting experiments to learn about electrons the _______________ in the atom that surround the nucleus. levels What he found was that the electrons are located in _________________ surrounding the nucleus. protons neutrons 2 Lesson 04 ­ Bohr­Rutherford Diagrams.notebook February 07, 2013 How to Draw Bohr­Rutherford Diagrams Step Example of that step 3 The outermost ring of electrons is called the __________________________ Lesson 04 ­ Bohr­Rutherford Diagrams.notebook February 07, 2013 4 Lesson 04 ­ Bohr­Rutherford Diagrams.notebook February 07, 2013 5 Lesson 04 ­ Bohr­Rutherford Diagrams.notebook February 07, 2013 6 Lesson 04 ­ Bohr­Rutherford Diagrams.notebook February 07, 2013 7
