Electron Affinity Trend
Is there an electron affinity trend on the periodic table, like the ones for atomic/ionic radii, electronegativity, and ionization energy?

Re: Rydberg Formula [ENDORSED]
In example 1.2, if you're going from n1=2 to n2=3 you are going up/increasing one energy level, therefore you're absorbing light and increasing in energy. In problem 1.13, you are using the same concept and formula ( E=-hR/n^2 and E= E(final)-E(initial) ) except for n1=4 and n2=2, where you are goin...

Re: Eienstein Equation Derived from E=mc^2 to E=(M*V)^2 [ENDORSED]
We know that the momentum is p=mv where m is the mass in kg and v is the velocity in m/s Energy (which can be converted from J to kg*m^2/s^2 derived from F=MA) is E=pv where p is the momentum in kg*m/s and v is velocity in m/s (recall that p=mv from the above equation), and we multiply again by v wh...
