🧠 IUPAC roots decode the atomic number digit by digit
Each syllable in the name stands for one digit: un = 1, nil = 0, bi = 2, tri = 3, quad = 4, pent = 5, hex = 6, sept = 7, oct = 8, enn = 9.

🗺️ Decode and find the group
"Unununnium" → un-un-un-ium → digits 1, 1, 1 →  (Roentgenium, Rg).

Expected Configuration as per Aufbau Rule: 
.

Actual Configuration: (You will study more about it in D&F block)
.
For d-block elements, 
group number  electrons .
