Final answer:
The correct noble gas electron configuration for nobelium (No) is [Rn]7s²5fⁱ⁴.
Step-by-step explanation:
The electron configuration for nobelium (No), which has an atomic number of 102, can be written in the noble gas configuration format. Since Nobelium is in the actinide series, the nearest noble gas prior to Nobelium is radon (Rn). Thus, its electron configuration starts with [Rn], followed by the configuration of the remaining electrons. Nobelium has 102 electrons, and the correct configuration is [Rn]7s²5fⁱ⁴, with the 7s and 5f orbitals containing the valence electrons beyond the radon core.
