Answer to Question #36561 in Quantum Mechanics for stereo-total-music

Question

Hello,
I've got a trivial question about electron's kinetic energy in atom. It's kinetic energy is
Ek=(p^2)/2m
, where "2m" is a constant (non-relativic visualization). The uncentainer position of electron (e.g. in larger molecule), the certainer momentum of it - certainer, but not bigger or smaller. So what is the math formula for smaller kinetic energy (behind covalent bond, for exmaple), is it:
Ek=(⌂p^2)/2m
Or are the limits simultaneously bigger, smaller with change of uncertainty?
Thank you.
