chemistry Flashcards
who was the Austrian scientist that worked in vienna, advanced atomic structure further w/ his theory of atomic orbitals, published his work on the topic in 1926, he also fled austria from the nazis, his model is still used as the accepted model of the atom?
Erwin Schrodinger “Quantum Mechanics”
who was curious abt the charge and mass of the nucleus, and lead to the discovery of the neutron?
James Chadwick
who used a CRT to determine an unknown beam of light had a charge and a very small mass?
JJ Thomson
who advanced atomic structure further w/ his theory of atomic orbitals?
Erwin Schrodinger
who was the danish physicist who worked at uni of copenhagen, helped jewish refugees flee nazi germany in WWI. developed the bohr model of the atom. he developed experiments w/ the light electrons emitted to help understand electron shells?
Neils Bohr
who worked with JJ Thomson and designed an experiment to test thomson’s theory of electrons?
Earnest Rutherford
who found the electron in 1897 and did research at cavendish labs. he used a CRT to determine an unknown beam of light had a charge and a very small mass. developed the “plum pudding” model of the atom
JJ Thomson: finder of the 1st particle
who developed experiments w/ the light electrons emitted to help understand electron shells?
Neils Bohr
who discovered the neutron?
James Chadwick
who worked with thomson, he designed an experiment to test thomson’s theory of electrons and discovered the nucleus of an atom with the “gold foil experiment” he proposed a 2nd model now called “jimmy neutron” model of the atom?
Earnest Rutherford
who proposed a groundbreaking theory entitled the 5 postulates of atomic theory in 1820
John Dalton: British, Quaker, and Bocce player
who was curious abt the charge and mass of the nucleus?
James Chadwick
who was the ancient philosopher that used sand from the beach to develop theory and coined the term “atomos”. His theory of atomos was deemed “crazy” and eventually cost him his reputation
Democritus: Greece, roughly 420 BC
who discovered the nucleus of an atom with the “gold foil experiment” and proposed a 2nd model now called “jimmy neutron” model of the atom?
Earnest Rutherford
who developed the “plum pudding” model of the atom
JJ Thomson
