The Top 10 Most Abundant Elements in the Entire Known

This basic list of ten elements is the “heaviest” for its density of each cubic cm

However, note that density is not mass, it just describes how tightly packed the mass is

Now that we understand that, let’s take a look at the heaviest elements in the entire known universe (The main image is a bismuth crystal that didn’t make the list)


10 – Tantalum (density per cubic cm: 1667g)

The atomic number of tantalum is seventy-three


9 – Uranium (density per cubic cm: 1905g)

Discovered in 1789 by the German chemist Martin H

8 – Tungsten (density per cubic cm: 1926g)

Tungsten exists in four different minerals and is also the heaviest of all elements known to play a biological role


7 – Gold (density per cubic cm: 1929g)

They say money doesn’t grow on trees, but gold does!

Small traces of gold were found in eucalyptus leaves

6 – Plutonium (density per cubic cm: 2026g)

The chameleon of the elements

5 – Neptunium (density per cubic cm: 2047g)

Named after the planet Neptune, it was discovered by Professor Edwin McMillan in 1940

It was also the first synthetic transuranic element from the actinide series to be discovered

4 – Rhenium (density per cubic cm: 2101g)

Rhenium comes from the Latin ‘Rhenus’ meaning ‘Rhine’ and was discovered by Walter Noddack in Germany in 1925


3 – Platinum (density per cubic cm: 2145g)

One of the most precious metals on this list (besides gold) and is used to make almost everything

Not much actually (try doing that with gold)

2 – Iridium (density per cubic cm: 2256g)

Discovered in London in 1803 by Smithson Tennant, he found it in the residue left when raw platinum was dissolved!

Yes, discovered purely by chance


1 – Osmium (density per cubic cm: 2259g)

It does not get any heavier (per cubic cm) than osmium

Strangely, its name comes from the Greek term osme, which means smell!
