2 interactive concept widgets for The p-Block Elements. Drag any slider, change any number, and watch the formula and the answer update live. Built so you understand how each NEET problem actually works, not just the final number.

Explore atomic radius, electronegativity, electron gain enthalpy, boiling point, and bond dissociation energy across Groups 15, 16, and 17. Visual bar charts highlight anomalies like the F2 bond energy anomaly (F-F less than Cl-Cl) and the O/F electron gain enthalpy anomaly.
Explore periodic trends across Group 15, 16, and 17. Select a group and a property to see bar charts, trend direction, and NEET-critical anomalies like the F2 bond energy anomaly.
Trend: Increases down the group
As you go down, more electron shells are added, increasing atomic size. N is much smaller than P because N is period 2 with no d orbitals.
