(a)
Interpretation:
The number of unpaired electrons present in lead atom has to be predicted.
Concept Introduction:
Electronic configuration: The electron configuration is the distribution of electrons of an atom or molecule in atomic or molecular orbitals.
Electrons occupy the lowest energy orbitals. The increasing order of orbital energy is
The energy order of the orbital for the first three periods is as follows,
The orbital which is closer to the nucleus has lower energy; therefore the
In general, the orbitals can hold maximum of two electrons, the two electrons must have opposite spin.
The subshell ordering by Aufbau principle is given below,
(b)

Chemical Principles: The Quest for Insight
- What are quantum numbers? What information do we get from the quantum numbers n, l, and ml? We define a spin quantum number (ms), but do we know that an electron literally spins?arrow_forward6.103 Atomic absorption spectroscopy is based on the atomic spectra of the elements being studied. It can be used to determine the impurities in a metal sample. If an element is present, light at the appropriate wavelength is absorbed. You are working with a metal stamping company and the rolled steel you use to form panels for automobile doors is failing at an alarming rate. There is some chance that the problem is unacceptably high levels of manganese in the steel. Given that the atomic spectrum of manganese has three lines near 403 nm, how could you use a spectrometer to determine the amount of manganese in the steel?arrow_forwardSuppose that the spin quantum number did not exist, and therefore only one electron could occupy each orbital of a many-electron atom. Give the atomic numbers of the first three noble-gas atoms in this case.arrow_forward
- State which of the following orbitals cannot exist according to the quantum theory: 3p, 4s, 2f, and 1p. Briefly explain your answers.arrow_forwardWhat is the maximum number of electrons that can occupy a f subshell (l = 3)?arrow_forwardWhat does wave-particle duality mean? What are its implications in our modem view of atomic structure?arrow_forward
