Get started for freeIn Rutherford's alpha-particle scattering experiment: (a) How did he interpret the observation that only a very few of the \(\alpha\) particles were scattered by the gold foil and most of them went straight through? (b) What was wrong with his model of the atom as far as the physics of the day was concerned?
For each pair, indicate which atom loses an electron more easily: (a) \(\mathrm{Na}\) or \(\mathrm{K}\) (b) Na or Al (c) \(\mathrm{Rb}\) or \(\mathrm{Ca}\) (d) \(\mathrm{S}\) or \(\mathrm{Cl}\) (e) Br or Kr
How many elements are in each transition metal period of the periodic table? How many are in each lanthanide (rare earth)/actinide period?
Explain the major difference between Thomson's model of the atom and Rutherford's model. Draw a picture of each model.
If one considers just the representative elements, how many groups would the periodic table have?
