Using the PhET hydrogen atom simulation to test ideas from classical and quantum physics

Scientists make observations of the world around them. Based on those observations, they often develop models of the phenomena they observe. In this activity, you will:

develop characteristics of a model for the hydrogen atom.

test different models, comparing them to your model and your observations.

Q7 Does one or more of the above models match the results of the experiment in the first part of this activity? Does one or more of the above models have similar components to your model? Which ones?

Q8 Based on your observations in the first part of the experiment, are any of the above models highly unlikely to match the actual hydrogen atom? Which one(s)? Why?

Q9 What can you definitely conclude about the make-up of the hydrogen atom based on this simulation?

Solution

Q. NO. 7.

Ans - yes, Bohr , De-broglie , and Schrodinger model of the atom show similarity for the quantisation of energy. In all these model energy of the atom are quantised that also verified the experimental facts.

Q.NO. 8

Ans - yes, Schrodinger model of atom match highly to the actual hydrogen atom.

Bhor\'s model of atom gives the incorrect value for the angular momentum for ground state that is not verifing the experimental facts but ,by shrodinger model of atom, it is resolved by quantising the space( phase space).

Shrodinger model also result the quantisation of energy and give a probalistic veiw of the orbit of the electron in the atom and its model at various state( energy) of the atom that highly match with experiment and by this way, Zeeman effect, stark efect etc have been explained( intereaction of atom with magnetic field and electric field).

Q.No, 9

Ans- Billiard ball model, solar system model, and plum pudding model does not verify various phenomena of the atom. bohr\'s model and debroglie model verify some of it ( as energy and duality charcter of nature of matter) but it does not explain the all spectral behaviour of the hydrogen atom.

but by shrodinger model of atom. it explain various experimental facts of the atom.So, most popular ( accepted) theory is shrodinger model.
