Ununoctium has the atomic number 118, and is an artificially produced element. It has yet to receive an official name and all properties have not yet been dicovered.
On the other hand,
Hydrogen is the least dense element.
Hydrogen has the atomic number 1, and is represented by symbol H. It's density is only 0.00008988 g/cm3.

What are the 3 least dense elements on the periodic table?
The three least dense elements on the periodic table are hydrogen, helium, and lithium. These elements have low densities because they consist of light atoms with few protons and neutrons in their nuclei.
Which is the least dense?
Helium is the least dense element at normal conditions.
In order to least to most dense water mercury gold lead?
For lead slight tank in hardness also. But, if gray deliver case joint or north density for a.
What part of the periodic table is the most reactive and least reactive?
The alkali and alkaline earth metals are the least electro negative elements, and the halogens are the most electro negative elements.
Where are the most dense metals on the periodic table?
Osmium is the densest of the elements. The most dense pure metal is osmium, Os, with a density of 22.61 g/cm3 (that's about twice the density of lead).Other very dense metals are:iridium, Ir, 22.56 g/cm3platinum, Pt, 21.4 g/cm3rhenium, Re, 21.0 g/cm3neptunium, Np, 20.4 g/cm3plutonium, Pu, 19.8 g/cm3gold, Au, 19.3 g/cm3tungsten, W, 19.3 g/cm3mercury, Hg, 13.53 g/cm3Lead, Pb, which is usually considered pretty dense, is only 11.4 g/cm3! In case this isn't enough, lead will float on liquid mercury, which has a density of 13.5 g/cm3.
What is the 3 least dense elements on the periodic table?
What ARE the 3 least dense elements on the periodic table. Science doesn't matter. Language Arts does. :) Hope this helped
Is Earth the least dense of all planets?
No. In fact it is the most dense planet. The least dense is Saturn.
What are Earths layers from outermost going inward?
From most dense at the core to least dense proceeding outward.
Is it true that the least dense minerals are found in earth's core?
No. The denser minerals are found at the core.
What is mercury water gold and oxygen from densest to the least dense?
(most dense to least dense) gold, mercury, water, oxygen
What gas is the most or least dense when heated?
When heated, gases typically expand and become less dense. So, a gas would be least dense when heated.
What element has the lowest denisty of all of the elements?
Hydrogen is the least dense of all the elements and all other known substances.
Where does most of our knowledge about the earth come from?
Name the layers of earth in order from most dense to least dense
What element has the lowest density of all of the elements?
The element which has been measured to have the lowest density is hydrogen. Not only is hydrogen the least dense element, it is also the most plentiful on earth.
Is the inner core the least dense layer of the earth?
The core is the most dense layer
What is the least dense crust outer core mantle or the inner core?
The crust is the least dense. The inner core is the most dense. So from the middle outwards the layers get less and less dense
Where would you find the least dense elements in a star?
Denser elements in a star tend to condense near the star's core, while less dense elements generally move outward towards the surface to take place in nuclear fusion.
