What you practice

These are the CBSE Class 11 Classification of Elements & Periodicity skills this quiz is built around.

Locate s, p, d and f blocks from electronic configuration.
Predict size, ionisation and electronegativity trends across periods and groups.
Explain diagonal links and anomalous behaviour of second-period elements.

A useful tip

Atomic size shrinks across a period but grows down a group. Effective nuclear pull explains both moves: more protons tighten, while new shells loosen the hold.
