a) The energy of the 2s state of some element is -5.691eV. Compute the value of Zeff for this state.
b) The energy of the 4s state of some element is-4.339 eV. Compute the value of Zeff for this state.
c) Compare Zeff for the 2s state of lithium, the 3s state of sodium, and the 4s state if potassium. What trend do you see?
Zeff becomes smaller going down the columns in the periodic table. Zeff remains constant going up or down the columns in the periodic table. Zeff becomes larger going down the columns in the periodic table.
In the nuclear-fission reaction, neutrons are emitted, usually some number of neutrons between 0 and 5. The process is thought to be random. First calculate the total number of fissions observed. Then calculate the average number of neutrons per f..
