What is a representative element?
The representative elements are elements where the s and p orbitals are filling. The transition elements are elements where the d orbitals (groups 3–11 on the periodic table) are filling, and the inner transition metals are the elements where the f orbitals are filling.
How do you find density on the periodic table?
We can work out the density of an object by dividing the mass of the object by the known volume. If we examine two different elements for example Iron and water. Iron has a density of 7.874 g/cm3 meaning that for every cm3 of volume there are 7.874 grams of iron in that volume.
What are the 10 densest elements?
The 10 Densest Metals:
- Osmium 22.6 g/cm^3. Similar to Iridium, osmium is a hard-brittle transition metal that looks bluish-white.
- Iridium 22.4 g/cm^3. What is this?
- Platinum 21.45 g/cm^3.
- Neptunium 20.2 g/cm^3.
- Plutonium 19.84 g/cm^3.
- Tungsten 19.35 g/cm^3.
- Gold 19.32 g/cm^3.
- Uranium 18.95 g/cm^3.

How do you identify representative elements?
Answer: The elements within the first two families (Groups I and II on the far left) and the last six families or groups (on the right) of the Periodic Table are known as representative elements. S-lock and P-block elements come under the category of representative elements.
What is the rarest man made element?
Oganesson is one of the rarest synthetic elements and only a few atoms have ever been produced. The radioactive element is highly unstable and has an extremely short half life of only 0.89 milliseconds (0.00089 seconds).
Which element is the most expensive?
The Five Most Expensive Elements in the World
- Francium – approximately $1 billion per gram. You might ask how could such an element be so expensive.
- Californium – $25 million per gram.
- Carbon – $65k per gram.
- Plutonium – $4k per gram.
- Scandium – $270 per gram.
