▸ The reading
interpretive · artRutherfordium honours the man who found the nucleus — and exists as almost nothing but nucleus, its half-lives counted in atom-events rather than grams. Chemistry performed one atom at a time shows it behaving like hafnium, the periodic law holding past the actinides. The table's structure, stress-tested and still true.

▸ Discovery
Berkeley (Ghiorso et al.) claimed 1969; Dubna had claimed earlier discoveries the IUPAC eventually rejected · United States (with Soviet dispute) · 1969 (disputed)
▸ Stellar origin
Human-madeFirst transactinide. Synthesized by heavy-ion fusion; longest-lived isotope has a 13-hour half-life.
▸ Reactivity
Behaves like hafnium, confirming periodic trends past 7th rowFirst synthesized element whose chemistry was tested atom-by-atom in gas-phase experiments — and it cooperated by acting like its row-4 homologue Hf.
▸ Applications
- Confirming relativistic periodic-trend predictions
- Heavy-element chemistry research
- (No commercial applications)
- (No practical bulk uses)
▸ Curiosity
Named for Ernest Rutherford, who discovered the atomic nucleus — and an element whose half-life is measured in atom counts rather than masses.
