Problem 50E

Problem 50E

The smallest atoms can themselves exhibit quantum- mechanical behavior Calculate the c Broglie wavelength (in pm) of a hydrogen atom traveling at 475 m/s.

Step-by-Step Solution:
Step 1 of 3

SolutionStep1Electron affinityThe energy change that happens when an electron is added to a gaseous atom is called aselectron affinity.A negative value of electron affinity means that there is a decrease in potentialenergy with the addition of the electron.In other words energy is released by theatom.Consequently the atom becomes more stable.(Energy and stability is inverselyrelated.Lower the energy greater will be the stability.)Thus if the electron affinity for an element is a negative number, it means that the anion of theelement is more stable than the neutral atom.
