⚗️ Chemical Elements

Name the symbol for every element.

Group: Nonmetals & halogens (13) · Noble gases (7) · Alkali & alkaline earth (12) · Post-transition & metalloids (18) · Transition metals (38) · Lanthanides & actinides (30).

One hundred and eighteen squares, no more and no fewer: the periodic table is the only syllabus in the society that is provably complete. Each question names an element and asks for its symbol, and the grading follows the table's own logic. The first marks are honest abbreviations — H, He, C, O — and then Latin starts collecting its debts. Copper is Cu for cuprum, iron Fe for ferrum, lead Pb for plumbum; silver, gold, tin and mercury all answer to names a Roman would recognise and a modern student must simply memorise. The bank is organised by group — alkali metals to noble gases, the long middle country of the transition metals, and the lanthanides and actinides where thirty questions live and most streaks die. Tungsten is W and the reason is German; sodium is Na and the reason is Latin by way of soda. Nothing here is a trick: the symbols derive from the element names by design, which is exactly why the validator excuses them and the examiner does not. It is the cleanest test of pure recall the society offers, the one bank where every question has always had exactly one answer since the day the element was named. Run it at five questions for a warm-up or all one hundred and eighteen for a census of your chemistry. The table does not change; your score can.
