Wave Nature Of The Electron Flashcards
Who was the first to suggest that all moving particles have a wave motion associated with them?
Louis de Broglie
What was Louis de Broglie’s contribution to science?
He suggested that all moving particles have a wave motion associated with them
What is often referred to as ‘wave-particle duality?
The idea that a particle can behave like a wave
What is the idea that a particle can behave like a wave referred to as often?
Wave-particle duality
What is the main reason that Bohr’s theory was not completely correct?
If the electron has a wave motion, then Bohr’s picture of it travelling in a precise path at a precise distance from the nucleus cannot give a full picture of the situation
Who put forward the Heisenberg Uncertainty Principle?
Werner Heisenberg
What was Werner Heisenberg’s contribution to science?
He put forward the Heisenberg’s Uncertainty Principle
What is Heisenberg’s Uncertainty Principle?
Heisenberg’s Uncertainty Principle states that it is impossible to measure at the same time both the velocity and the position of an electron
What comment did Heisenberg make about Bohr’s theory?
He said Bohr’s picture of the atom was not completely satisfactory
Why was Bohr’s model of the atom considered unsatisfactory by Heisenberg?
As Bohr’s model visualised electrons moving with a certain speed in orbits of fixed distances from the nucleus
Why did Heisenberg believe Bohr’s model was unsatisfactory?
As you cannot measure at the same time both the speed and distance from the nucleus of an electron
If the electron is not travelling in a fixed path, what is the only way we can talk about electron and their location?
We can only talk about the probability of finding an electron at a particular position inside the atom
