Delta X

Postby Jennifer Tuell 1B » Wed May 09, 2018 12:14 pm

I know when delta x is given as +/- 3 for example you multiply the number by 2 for the equation, but when you are given the radius of an atom do you plug in the radius or the diameter into the equation?

I believe it would be the entire diameter because the electron can be within that entire diameter of an atom. It would not make physical sense for the electron to be limited to only half the atom.

Someone asked about this in class and the answer was to plug in the diameter.

You plug in the diameter for delta x because it gives you a range of where the particle could be without telling you the exact position of the object you are looking for. Think of this concept as a different version of the velocity's uncertainty with their plus, minus value. The plus-minus is exactly like the radius where you multiply it by 2 to get your full range of the uncertain position.

I hope this helps. Correct me if I am wrong in certain places.

You plug in the diameter. In the same way +/-3 gives you six, +/- the radius gives you the diameter (you multiply by 2).
