Dalton
Dalton's first name
What is John?
Name of model
What is the Plum Pudding Model/Thomson's model?
Name of Model
What is Rutherford's atomic model?
Name of model
What is Bohr model?
Name of Schrodineger's model
Name of Chadwick's model
What is the Electron Cloud Model, and the Quantum Mechanical Model?
Name of Dalton's Model
Billiard Ball Model
A beam of particles was sent through a tube. It was attracted to the positive side when a charge was present.
Description of model
What isthe nucleus is small and dense, and electrons orbit the nucleus like planets orbiting the sun?
Description of model
What is electrons orbit the nucleus and their energy levels?
Description of Schrodinger's model and Chadwick's model
What is Electrons are difficult to predict and that orbits are more complex. Schrodinger used math. Chadwick determined there was another particle with a neutral charge had the same mass as a proton. This "proton" became known as the neutron?
Description of experiment
He experimented with different substances to see if their proportions styed the same. Like water 1 oxygen and two hydrogens equal water ratio 1:2.
Electrons
What is electrons were mixed throughout the atom. Electrons have a negative charge. First statement we later found out was incorrect.?
Description of experiment
What is fired alpha particles/helium nuclei piece of gold foil only a few atoms thick most passed through about one in twenty thousand bounced back?
Descriptions of experiment
What is when an electron moves closer to the nucleus it emits light.
Descriptions of their experiments
What is, Schrodinger used math equations instead to predict the likelihood of electron position? Chadwick bombarded Beryllium atoms with alpha particles and an unknown radiation was produced?
Gained understanding about the atom
Elements combine in certain proportions because they are made of single atoms.
Experiment description
What is Used/made a Cathode Ray. Create a glass vacum tube, run electricity through until charged plates then it bends toward positivley charged plate. On bottom?
Understanding change
What is electrons orbit the nucleus just like planets are pulled by gravity to orbit the sun. Technically false.?
Our understanding changes/increases.
Added energy levels divide up the electrons around the nucleus?
How they changed our understanding?
What is, Schrodinger showed us that electron clouds are the areas that an electron is most likely to be found? Chadwick showed us that neutrons do in fact exist and still used Schrodinger's mathematical electron orbitals?
Description of model
What is atoms are small particles that are identical if they are the same element?
The results of this experiment changed our understanding of the atom.
What is this proved the existence of electrons and that atoms are made of smaller particles?
Favorite model or hate them all
What is hate them all/ Dalton, Thomson, Rutherford, Bohr, Schrodinger, Chadwick?
