(a) Interpretation: The ground state electronic configuration of tellurium needs to be determined. Concept introduction: According to Aufbau principle, electrons are filled first in lower energy orbitals followed by higher energy orbitals. Hund’s rule states that, while filling electrons in degenerate orbital, there will be a single occupancy first and then only pairing can take place.

Solution Summary: The author explains Aufbau principle, where electrons are filled first in lower energy orbitals followed by higher energy.
Definition Definition Number of protons in the nucleus of an atom. It uniquely identifies an element, as the number of protons determines the element's properties. The periodic table of elements is arranged based on increasing atomic numbers, allowing scientists to easily locate and study elements.
