What is the meaning of Heisenberg’s Uncertainty Principle?
There is no way of knowing the position of an electron in an atom.
Well Done! Partial Correct Answer Correct Answer Incorrect Answer
The electron is too quick to be measured.
Well Done! Partial Correct Answer Correct Answer Incorrect Answer
You cannot precisely determine the velocity of an electron and its position in the atom at the same point in time.
Well Done! Partial Correct Answer Correct Answer Incorrect Answer
The electron is simultaneously in several places in the atom at once.
Well Done! Partial Correct Answer Correct Answer Incorrect Answer
Why does it appear as if the atom has a capsule surrounding it?
The electron has the possibility of being at different specific locations around the atom simultaneously.
Well Done! Partial Correct Answer Correct Answer Incorrect Answer
The electrons’ density is very high and so they look like a capsule.
Well Done! Partial Correct Answer Correct Answer Incorrect Answer
There are elemental particles surrounding the atom together and this gives the appearance of a capsule.
Well Done! Partial Correct Answer Correct Answer Incorrect Answer
A single electron becomes a capsule surrounding the atom.
Well Done! Partial Correct Answer Correct Answer Incorrect Answer
What behaves like a wave but is actually a particle?
The existence of the particle is like a wave.
Well Done! Partial Correct Answer Correct Answer Incorrect Answer
The particle moves on a wave.
Well Done! Partial Correct Answer Correct Answer Incorrect Answer
The particle moves up and down like a wave.
Well Done! Partial Correct Answer Correct Answer Incorrect Answer
The shape of the particle is wave-like.
Well Done! Partial Correct Answer Correct Answer Incorrect Answer
When examining the minimum and maximum of a wave, how can it be described based on an existence chart of a particle?
The minimum and maximum describe the number of \times in which the particle will appear in the same position.
Well Done! Partial Correct Answer Correct Answer Incorrect Answer
The minimum and maximum describe when the particle will appear and when it will not.
Well Done! Partial Correct Answer Correct Answer Incorrect Answer
There is no connection between the wave and the particle.
Well Done! Partial Correct Answer Correct Answer Incorrect Answer
The minimum and maximum describe the velocity intensity of the particle.
Well Done! Partial Correct Answer Correct Answer Incorrect Answer
What is the difference between the description of the atom according to Schrödinger and the descriptions of Bohr and De Broglie?
Schrödinger managed to depict all the elements, while Bohr and De Broglie focused on the hydrogen atom.
Well Done! Partial Correct Answer Correct Answer Incorrect Answer
Bohr and De Broglie depicted more atoms than Schrödinger.
Well Done! Partial Correct Answer Correct Answer Incorrect Answer
Schrödinger described only the movement of the electron around the hydrogen atom.
Well Done! Partial Correct Answer Correct Answer Incorrect Answer
There is no difference, they describe the same things.
Well Done! Partial Correct Answer Correct Answer Incorrect Answer
