I have the newest version and noticed some errors on #201 and 203.
#201 says that .20*60 is 1.2, when it is clearly 12. I got this one but I am not sure if #203 is wrong or not...
On #203, for choice e) it compares Sr++ with S-- and says that Sr++ is smaller in size than S--.... when Sr++ contains one more n principal quantum number than S--...
Comparing Sr++ with Se-- sounds right to me... Can someone clarify on #203 if the solution is right or not?
