Consider an electron in a 2s orbital of hydrogen (Z=1). Calculate the probability that the electron will be found anywhere in a shell formed by a region between a sphere of radius r and radius 1.0pm greater than the r value. Do this calculation in Excel for r from 1 to 600 pm in increments of 1pm. (You will be calculating the probability for successive shells at greater and greater distances from the nucleus.) Plot the resulting curve with probability...
