Summarize the history of the atomic idea. How was Dalton able to convince others to accept an idea that had been controversial for 2000 years?

Solution : (a) Calculation of the percent abundance of each element : Given, 293 red spheres are Nv. Blue spheres are 295Nv. There are 12 out of 20 red spheres i.e 293Nv. There are 8 out of 20 red spheres i.e 295Nv. We calculate the percentage abundance of each element as : 293 Percentage abundance of Red colored spheres- Nv : = 60 % Percentage abundance of BLue colored spheres- 295Nv : = 40 % (b) Atomic weight of Nv : Given, mass of 293Nv = 293.15...
