Which group elements exhibits highest densities?
Which group elements exhibits highest densities?
- A. IIIB
- B. Iv
- C. vı
- D. VIIIB
Step-by-step solution
Group VIIIB contains heavy platinum group metals like osmium, iridium, and platinum, which are the densest elements. Osmium and iridium have densities around 22.6 g/cm³, the highest of all elements. Other groups: IIIB includes lighter transition metals, IV (group 14) includes nonmetals and lighter metals, VI (group 16) includes nonmetals and metalloids, none of which approach these densities.
