Consider the electron in a 2p state (for simplicity, take m = 0) (i) consider whether and < 1/r> can be calculated by integrating only the radial part of the wavefunction. (ii) calculate the expectation value of the distance between the electron and the nucleus, (ii) calculate the expectation value of the reciprocal distance between the electron and the nucleus, < 1/r> . (iv) are the average potential energies of the electron in 2s and 2p states the same or different?

Laboratory experiments, observational field studies, and model-building are all examples of different forms of scientific investigations.  in what way do laboratory experiments primarily differ from other forms of scientific investigations?   a.  a laboratory experiment is the only accepted form of investigation within the scientific community.  b.  studies about how things behave in nature or studies involving very large objects are best answered through laboratory experiments.  c.  laboratory experiments involve the identification and control of variables.  d.  data can only be generated through laboratory experiments, not other forms of investigation.
