Explain what is meant by the photoelectric effect.
An electron in the hydrogen atom makes a transition from an energy state of principal quantum numbers \(n_{\mathrm{i}}\) to the \(n=2\) state. If the photon emitted has a wavelength of \(434 \mathrm{nm}\), what is the value of \(n_{\mathrm{i}}\) ?
What is the physical significance of the wave function?
What is meant by the term "shielding of electrons" in an atom? Using the \(\mathrm{Li}\) atom as an example, describe the effect of shielding on the energy of electrons in an atom.
Give the values of the four quantum numbers of an electron in the following orbitals: (a) \(3 s,\) (b) \(4 p,\) (c) \(3 d\).
