1. A proton is confined to a space 1 fm wide (about the size of the atomic nucleus). What is the minimum uncertainty in its velocity? 2a. Is it possible to determine an electron's velocity accurate t (a) Verify from its quark composition that the De...
(Atomic weights of N and H are 14 and 1.01, respectively.) What is the edge length of a simple cubic unit cell made up of atoms having a radius of 158 pm? What would be the radius of a 23892u nucleus if it had the density of the earth? Express your answer to three significant...
The energy in Bohr's atomic model is proportional to the square of the atomic number or proton number and is inversely proportional to the energy level squared. The proportionality constant is a combination of Planck's constant, electron mass, and electron charges. Answe...
