What element is heavy?
Why Osmium and Iridium Are So Heavy Even though there are many elements with higher atomic weight values, osmium and iridium are the heaviest. This is because their atoms pack together more tightly in solid form.

What are the 3 heavy elements?
This process, known as spallation, is how the lithium, beryllium and boron found on Earth was formed, and the only reason why these elements can be found at all on our planet. These three elements are by far the rarest of all the light elements, and this process is the only reason they’re around at all.
What is a super heavy metal?
Superheavy elements, also known as transactinide elements, transactinides, or super-heavy elements, are the chemical elements with atomic number greater than 103. The superheavy elements are those beyond the actinides in the periodic table; the last actinide is lawrencium (#103).
How many heavy metals are there?
Several definitions of heavy metals exist. There are about 40 heavy metals but the exact number depends on the definition used. Definitions are based on the density, atomic number or weight and/or toxicity.

What are the new names for superheavy elements?
After a five-month review, IUPAC chemists have approved the four names for superheavy elements 113, 115, 117 and 118 proposed by the elements’ discoverers. Such superheavy elements, whose atomic number s indicate how many protons reside in each nucleus, don’t occur naturally in nature, so they must be created in labs.
