How did he support his theory? $500 Answer from H1 Ernest Rutherford, through the Gold Foil Experiment $100 Question from H2 Protons have what kind of charge? $100 Answer from H2 positive $200 Question from H2 Which particles have about the same mass? $200 Answer from H2 Protons and neutrons $300 Question from H2 What unit is used for communicating the mass of the particles of an atom? $300 Answer from H2 Amu: atomic mass unit $400 Question from H2 How is the atomic mass of an atom determined? $400 Answer from H2 By adding the # of protons to the # of neutrons $500 Question from H2 How is the Atomic # for an element determined? Why doesnt the atomic # for an element ever change? $500 Answer from H2 It is the # of protons in an atom of the element. The # of protons in an atom of an element never changes $100 Question from H3 The sun is made up of mostly what element? $100 Answer from H3 Hydrogen $200 Question from H3 Briefly describe what happens during the process of nuclear fusion. $200 Answer from H3 Small nuclei combine(fuse) to form larger nuclei $300 Question from H3 Where did our solar systems matter, and the elements that make it, originate? $300 Answer from H3 A supernova, an explosion that broke apart a massive star billions of years ago. $400 Question from H3 In nuclear fusion two atomic nuclei combine And what is also released? $400 Answer from H3 Huge amounts of energy and neutrons $500 Question from H3 Stars are composed of a gas-like mixture of free electrons and atoms stripped of electrons called what? $500 Answer from H3 plasma $100 Question from H4 Who first organized a useful periodic table? $100 Answer from H4 Dmitri Mendeleev $200 Question from H4 Columns in the periodic table are called what? $200 Answer from H4 families $300 Question from H4 How did Mendeleev organize his periodic table? How did scientists later change this? $300 Answer from H4 Mendeleev organized it by increasing atomic mass. Later scientists organized it by increasing atomic number. $400 Question from H4 Mendeleevs periodic table was incomplete. What did Mendeleev predict would happen and did in? $400 Answer from H4 Scientists discovered 3 new elements which helped complete the periodic table. $500 Question from H4 What information can be found in each square of the periodic table? $500 Answer from H4 An elements atomic number, symbol, name and atomic mass. $100 Question from H5 As you move from hydrogen to radon on the periodic table what happens to the atomic numbers of the elements? $100 Answer from H5 They increase $200 Question from H5 The elements in a period move in which direction on the periodic table? $200 Answer from H5 Right to left, horizontal rows $300 Question from H5 Which group of elements react violently with Group 1? $300 Answer from H5 Group 17 $400 Question from H5 What can you say about the properties of elements that are in the same family? $400 Answer from H5 They have similar properties $500 Question from H5 Describe what happens to the elements as you move from right to left across the periodic table? $500 Answer from H5 The properties of the elements will change Final Jeopardy Why did the model of the atom and Mendeleevs periodic table change? Final Jeopardy Answer New technology and knowledge gained Through experiments allowed scientist to make improvements to the models
