Where is osmium found?

Sources of osmium Osmium is produced as a by-product of nickel refining. The element occurs in the mineral iridosule and in platinum-bearing river sands in the Urals, North America and South America. While there is little osmium in these products, it can be easily obtained from processed nickel ores.

Why is osmium the densest element?

Osmium is the most dense element because it has the most mass in the smallest amount of space. Density is mass divided by volume. An element with more neutrons will be denser, because neutrons have roughly the same mass as a proton.

What is 120th element?

According to this, Unbinilium, also known as eka-radium or element 120 in the periodic table, is a hypothetical chemical element with atomic number 120. … Unbinilium is projected to be less reactive than barium and radium and behave more like strontium. And hence Unbinilium is the 120th element in the periodic table.
