Describe the characteristics of an \(s\) orbital, a \(p\) orbital, and a \(d\) orbital. Which of the following orbitals do not exist: \(1 p, 2 s, 2 d, 3 p, 3 d, 3 f, 4 g ?\)
Give two everyday examples that illustrate the concept of quantization.
Calculate the wavelength (in nanometers) of a photon emitted by a hydrogen atom when its electron drops from the \(n=5\) state to the \(n=3\) state.
Explain what is meant by a noble gas core. Write the electron configuration of a xenon core.
When an electron makes a transition between energy levels of a hydrogen atom, there are no restrictions on the initial and final values of the principal quantum number \(n\). However, there is a quantum mechanical rule that restricts the initial and final values of the orbital angular momentum \(\ell\). This is the selection rule, which states that \(\Delta \ell=\pm 1,\) that is, in a transition, the value of \(\ell\) can only increase or decrease by one. According to this rule, which of the following transitions are allowed: (a) \(1 s \longrightarrow 2 s\), (b) \(2 p \longrightarrow 1 s\) (c) \(1 s \longrightarrow 3 d\) (d) \(3 d \longrightarrow 4 f\), (e) \(4 d \longrightarrow 3 s ?\)
