Classification of Elements & Periodicity · Class 11 · JEE Main Previous Year Question
The element with (not yet discovered) will be a/an:
- a
transition metal.
- b✓
alkaline earth metal.
- c
alkali metal.
- d
inner-transition metal.
alkaline earth metal.
🧠 After Z=118 (noble gas), the next two slots fill 8s Oganesson () is a noble gas, Period 7, Group 18. Period 8 starts with s-block: fills (Group 1), fills (Group 2).
🗺️ Classify Group 2 Group 2 elements are alkaline earth metals — so element 120 will be an alkaline earth metal, though undiscovered.
