Question

At what atomic number is the filling of a g orbital likely to begin?

Accepted Answer

Understand the concept of electron orbitals: Electrons in an atom fill up orbitals in a specific order based on their energy levels. The order generally follows the Aufbau principle, which states that electrons occupy the lowest energy orbital available.. Identify the types of orbitals: Orbitals are categorized into types such as s, p, d, and f. Each type of orbital has a different shape and energy level. The g orbital is another type that would theoretically follow the f orbital in terms of energy and complexity.. Recall the order of filling orbitals: The order in which orbitals are filled is s, p, d, f, and then g. Each type of orbital starts filling at different atomic numbers, with s orbitals starting at hydrogen (atomic number 1), p orbitals starting at boron (atomic number 5), d orbitals starting at scandium (atomic number 21), and f orbitals starting at cerium (atomic number 58).. Determine the starting atomic number for g orbitals: Based on the pattern of orbital filling and the periodic table, the g orbitals would begin to fill after the f orbitals. Since the f orbitals start at atomic number 58 and fill through elements with higher atomic numbers, the g orbitals would begin to fill at an atomic number higher than those that fill the f orbitals.. Apply the periodic table and theoretical predictions: As of now, g orbitals are theoretical and have not been observed in naturally occurring elements. They are predicted to start filling in the eighth period of the periodic table, which includes elements with atomic numbers higher than those currently discovered or confirmed.
