Section 1.3 Review Game Dollar : US :: Pound : 1.Italy 2.Britain 3.Norway 4.Spain John Dalton proposed which model of the atom in 1803? 1.Plum pudding model 2.Nuclear model 3.Solid sphere model 4.Solar system model 5.Proton model The observation that elements cannot be created or destroyed in chemical reactions supported which model of the atom? 1.Plum pudding model 2.Nuclear model 3.Solid sphere model 4.Solar system model 5.Proton model In 1897, J.J. Thomson discovered that a negative charge could be removed from the atom. This evidence led him to propose the _________________ model of the atom. 1.Plum pudding 2.Nuclear 3.Solid sphere 4.Solar system 5.Proton In 1911, Ernst Rutherford conducted the gold foil experiment in which he shot alpha particles at a thin sheet of gold foil. He found that 1.All particles went through 2.Most particles went through; a few bounced back 3.Few particles went through; most bounced back 4.All particles bounced back The evidence from the gold foil experiment led Rutherford to conclude the 1.Atom was neutrally charged 2.Electrons make up most of the mass of an atom 3.Atom has a dense negative nucleus 4.Atom is mostly empty space 5.All of the above Which is the most current model of the atom that we have been using in class? Which of the following uniquely defines an element? 1.Atomic mass 2.Atomic number 3.Number of protons 4.Number of neutrons 5.Mass number 6.Both 2 & 3 7.None of the above For an atom to be neutral, it must contain the same number of 1.Protons & neutrons 2.Protons & electrons 3.Electrons & neutrons 4.All three must be equal in number What accounts for most of the mass of the atom? 1.The electrons 2.The protons 3.The neutrons 4.The nucleus 5.All have equal size and mass Participant Scores 800Anna Lawrence400Kristen Crable 700Tanner Helms400Elle McCartney 700Kayleigh Rine400Morgan May 500Adelaide Burgess400Hannah Domanick 500David Meyer400Mark Armstrong 500Raisa Gregor300Jordyn Mihalik 500Madisen Paige300Wylyn McCullough 500Lindsey Schoch300Meghan Bird 500Joseph Bertolino200Emma Finley 500Hailey Seibel200Taylor Lair What percentage of your current points would you like to wager on the next question? 1.0% 25% 50% 75% 100% If the atom were the size of this then the nucleus would be the size of 1.A marble 2.A golf ball 3.A basketball 4.A very large beach ball 5.A hot air balloon 6.None of the above Participant Scores 1500Tanner Helms850Lindsey Schoch 1325Kayleigh Rine700Wylyn McCullough 1300Anna Lawrence700Morgan May 1100Joseph Bertolino500Taylor Lair 975Adelaide Burgess300Meghan Bird 900Kristen Crable250Hailey Seibel 900Elle McCartney225Jordyn Mihalik 900Mark Armstrong200Hannah Domanick 850Raisa Gregor50Emma Finley 850David Meyer0Madisen Paige Electrons are about half the size of protons but have the same amount of charge just opposite. 1.All true 2.Part 1 is true; Part 2 is false 3.Part 1 is false; Part 2 is true 4.All false Which of the following is NOT true? 1.Scientists have direct evidence for the structure of the atom. 2.Protons have a mass of about 1 amu. 3.Neutrons have a slightly larger mass than protons. 4.Neutrons have no charge.
