Either osmium or iridium is the densest element. It's not entirely clear which; theoretical calculations predict that one is slightly denser and experiments show that the other is denser... but the difference is so small that it's possible that tiny errors in measurement could reverse the order.
Osmium in a metallic form is extremely dense, blue white, brittle and lustrous even at high temperatures, but proves to be extremely difficult to make.Osmium metal has the highest melting point and the lowest vapor pressure of the platinum family.One cubic metre of osmium would weigh about 22.65 tonnes!

Neon
The heaviest element in group 16 is Polonium. It has an atomic number of 84 and is a rare, highly radioactive metal.
Francium is the heaviest of the alkali metals, with an atomic mass of 223 grams.
There are 94 naturally occurring chemical elements in the universe. These elements range from hydrogen, the most abundant, to uranium, the heaviest naturally occurring element.
Osmium oh-s-me-umm
Osmium has the highest density among metals so is heaviest metal.
The heaviest alkaline-earth metal is radium. Radium is a highly radioactive element and is the heaviest and most unstable of the alkaline-earth metals.
No.
It is not. It is the lighest.
through my knowledge osimum is the heaviest metal
Barium is the heaviest non-radioactive alkali Earth metal, with an atomic number of 56.

By density, osmium is the heaviest (22.61 kgL-1). By atomic weight, ununpentium is the heaviest (228gmol-1)

Neon
Barium is the second heaviest alkaline earth metal, following radium in terms of atomic weight.
