Question

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?

Explanation / Answer

7)    The first model   have similar components to the model .

8) The second and fourth models are highly unlikely to match the actual hydrogen atom .

9)   The first hydrogen atoms in space gradually grouped together into clumps called nebulae. When a nebula got dense enough, it formed a star. Pure hydrogen gas is scarce in Earth's atmosphere and any hydrogen that actually enters the atmosphere rapidly escapes Earth's gravity .On our planet, hydrogen occurs mainly in combination with oxygen and water, as well as in organic matter such as living plants, petroleum and coal .
