I recommended watching the Fringe TV show, season 3 ep Os. It has a plot in it where an aerodynamic scientists combines the the two densest elements to become an element lighter than air.
Osmium is slightly denser than Iridium. Osmium has a density of around 22.59 g/cm3, while Iridium has a density of approximately 22.56 g/cm3. Both elements are among the densest naturally occurring elements.
a dense material has lots of particles in a small volume
Osmium is slightly more dense than Iridium by a small fraction.

By 'family' , I query your meaning. However, osmium is a d-clock element ( transition element) . It is Group 8 , Period 6.
osmium and iridium
osmium and iridium
Either osmium or iridium. It's a pretty close call. Theoretically iridium should be more dense; actual measurements indicate that osmium is very slightly denser.
Either osmium or iridium. The densities are very close.
These metals are three: ruthenium, iridium, osmium.

The element used to harden pen points is commonly iridium. Iridium is a dense and corrosion-resistant metal that is often alloyed with other metals to create durable pen nibs that retain their shape and provide a smooth writing experience.
Osmium and iridium are the two elements with highest density.

Osmium is slightly denser than Iridium. Osmium has a density of around 22.59 g/cm3, while Iridium has a density of approximately 22.56 g/cm3. Both elements are among the densest naturally occurring elements.
Aerogel, i think. It may be hydrogen.
Iridium can form alloys with copper.
