History of the Model of the Atom

He arranged the elements on the periodic table based on atomic number.

• Henry Moseley

• JJ Thomson

• Dmitri Mendeleev

• Dalton

• Niels Bohr

He arranged the elements on the periodic table based on atomic mass.

• Henry Moseley

• JJ Thomson

• Dmitri Mendeleev

• Dalton

• Niels Bohr

He said electrons travel in fixed orbits around the nucleus of the atom.

Who developed the Plum Pudding Model; atom is positive sphere with negatively charged particles evenly embedded throughout?

• Schrodinger and Heisenberg

• JJ Thomson

• Ernest Rutherford

• Dalton

• Niels Bohr

Who developed the Solid Sphere Model; elements are atoms with different masses?

• Schrodinger and Heisenberg

• JJ Thomson

• Ernest Rutherford

• Dalton

• Niels Bohr

Who developed the Nuclear Model; Gold Foil experiment allowed him to discover that the nucleus was the positively charged center of the atom surround by negatively charged electrons?

• Schrodinger and Heisenberg

• JJ Thomson

• Ernest Rutherford

• Dalton

• Niels Bohr

Who developed the Electron Cloud Model; surrounding the nucleus is an electron cloud made of shells – electrons do not, however, travel in a fixed orbit?

• Schrodinger and Heisenberg

• JJ Thomson

• Ernest Rutherford

• Dalton

• Niels Bohr

Who named the atom based on the Greek word meaning indivisible?

• Democritus

• JJ Thomson

• Ernest Rutherford
