How do you find the density of Flerovium?
Density of Flerovium is –g/cm3. In words, the density (ρ) of a substance is the total mass (m) of that substance divided by the total volume (V) occupied by that substance. The standard SI unit is kilograms per cubic meter (kg/m3).

Which is more harmful flerovium or ununquadium?
Flerovium is harmful due to its radioactivity. Flerovium is a synthetic radioactive metal and has only been produced in minute amounts. Flerovium is of research interest only. Source: Flerovium / Ununquadium is a synthetic radioactive metal, created via nuclear bombardment, and has only been produced in minute amounts.
Where did the element flerovium get its name?
Flerovium. Flerovium is a superheavy artificial chemical element with the symbol Fl and atomic number 114. It is an extremely radioactive synthetic element. The element is named after the Flerov Laboratory of Nuclear Reactions of the Joint Institute for Nuclear Research in Dubna, Russia, where the element was discovered in 1998.
What are the chemical properties of flerovium group 14?
Initial chemical studies performed in 2007–2008 indicated that flerovium was unexpectedly volatile for a group 14 element; in preliminary results it even seemed to exhibit properties similar to those of the noble gases.
Which is the most stable isotope of flerovium?
The most stable known flerovium isotope, flerovium-289, has a half-life of around 1.9 seconds, but it is possible that the unconfirmed flerovium-290 (with one extra neutron) may have a longer half-life of 19 seconds; this would be one of the longest half-lives of any isotope of any element at these farthest reaches of the periodic table.
