What does flerovium look like?
What does flerovium look like?
Flerovium can only be found in very special laboratories because it decays so rapidly. Despite the large size of its atoms, no one has seen flerovium so no one knows what it looks like. However, this element is predicted to be a silvery white or pale grey solid (probably) at room temperature.
What is the abundance of flerovium?
Abundance and Isotopes Flerovium is produced by bombarding 244Pu with 48Ca in a heavy ion accelerator. Isotopes: Flerovium has 5 isotopes whose half-lives are known, with mass numbers from 285 to 289. None are stable. The most stable isotope is 289Fl, with a half-life of 2.6 seconds.
Where is flerovium in the periodic table?
What is Flerovium? Flerovium with atomic number 114 and symbol Fl. It is a radioactive, superheavy synthetic element placed in the group 14 and period 7 of the periodic table.
How do you make flerovium?
Flerovium has five isotopes with known half-lives. To make flerovium, atoms of plutonium (Element 94) are bombarded with ions of calcium (Element 20) contained in a beam.
How do you write the electron configuration for flerovium?

What is the atomic number of flerovium?
Summary Element Flerovium Atomic number 114 Atomic mass [amu] 289 Atomic mass [pm] 175 Density at STP [g/cm3] 14
What is the valence electron configuration for Group 14 element flerovium?
Every previous group 14 element has four electrons in its valence shell, forming a valence electron configuration of ns 2np 2. In flerovium’s case, the trend will be continued and the valence electron configuration is predicted to be 7s 27p 2; flerovium will behave similarly to its lighter congeners in many respects.
Is flerovium a meta-stable isomer?
It is possible that it was the meta-stable isomer 287m Fl or the result of an electron capture branch of 287 Fl leading to 287 Nh and 283 Rg. The now-confirmed discovery of flerovium was made in June 1999 when the Dubna team repeated the first reaction from 1998.
What is the mass of a hydrogen-like flerovium ion?
The electron of the hydrogen-like flerovium ion (oxidized so that it only has one electron, Fl 113+) is expected to move so fast that it has a mass 1.79 times that of a stationary electron, due to relativistic effects. For comparison, the figures for hydrogen-like lead and tin are expected to be 1.25 and 1.073 respectively.
