Heisenberg Uncertainty Principle • An electron has a mass of 9.11 x 10-31 kg and moves at an average speed of 5 x 10 m/s. Let's assume we know the speed to an uncertainty of 1%. • Calculate the uncertainty in the position of the electron. (4x)(mAv) 24 Friendly Reminders...
German physicist Werner Heisenberg related the uncertainty of an object's position (Ax) to the uncertainty in its velocity (Av) h Дх > 4лтAu where his Planck's constant and m is the mass of the object The mass of an electron is 9.11 x 10-31 kg. What is the uncertainty in the position of an electron moving at 7.00 x 106 m/s with an uncertainty of Au = 0.01 x 106 m/s?
If an electron's position is known with small uncertainty, then the Heisenberg Uncertainty Principle predicts that .. O its momentum can be known with a small uncertainty the uncertainty in its position divided by the uncertainty in its momentum is larger than a fixed value its momentum can only be known with a large uncertainty -/1 points Which is correct? O most of an atom's mass and volume are in the nucleus which has a positive charge most of an...
2) The Heisenberg uncertainty principle states that A) matter and energy are really the same thing B) it is impossible to know anything with certainty C) it is impossible to know both the exact position and momentum of an electron D) there can only be one uncertain digit in a reported number E) it is impossible to know how many electrons there are in an atom 3) The n - 2 to n-6 transition in the Bohr hydrogen atom corresponds...
(20 points) Treat the hydrogen atom as a one-dimensional problem, where the electron is confined to the diameter of the atom in the first excited state (n-2). a.) Use the uncertainty principle to estimate the minimum kinetic energy of an electron in this state, assuming that the uncertainty in position equal to it's diameter. (Note: Relativistic corrections are not necessary). b.) Assuming this excited electron only remains in this state for 0.1 ns, before emitting a photon and returning to...
