What is the atomic radius of francium?
348 pm
Francium/Van der Waals radius
What is calculated atomic radius?
Atomic radius is determined as the distance between the nuclei of two identical atoms bonded together. The atomic radius of atoms generally decreases from left to right across a period. The atomic radius of atoms generally increases from top to bottom within a group.
Which element has the atomic radius?

Boron/Atomic radius
What is 87 on the periodic table?
Francium
Francium, number 87, was the last of these elements to be discovered in nature.
What is coulombic attraction?
Coulombic attraction is a fancy name for the attraction that occurs between oppositely charged particles. In chemistry, we talk about the attraction between protons (+) in the nucleus to the electrons (-) surrounding the nucleus.
Which atom has largest atomic radius?
francium
Atomic radii vary in a predictable way across the periodic table. As can be seen in the figures below, the atomic radius increases from top to bottom in a group, and decreases from left to right across a period. Thus, helium is the smallest element, and francium is the largest.
Why is it called livermorium?
The element is named after the Lawrence Livermore National Laboratory in the United States, which collaborated with the Joint Institute for Nuclear Research (JINR) in Dubna, Russia to discover livermorium during experiments made between 2000 and 2006. In the periodic table, it is a p-block transactinide element.
What is the atomic number of the element UUO?
Name: Ununoctium. Symbol: Uuo. Atomic Number: 118. AtomicWeight: 293.000000. Family: Noble Gases. CAS RN: 54144-19-3. Description: A very short lived super heavy element, appearance unknown.
What is the atomic number of ununoctium?
Oganesson. Ununoctium is a transactinide chemical element with symbol Uuo and atomic number 118. It was first created by a joint team of American and Russian scientists at the Joint Institute for Nuclear Research in Dubna, Russia.
What is the temporary IUPAC symbol for ununoctium?
Its temporary IUPAC element symbol is Uuo. Only three atoms of this element have been detected. The name ununoctium is a systematic element name, used as a placeholder until it will be confirmed by other research groups and the IUPAC decides on a name.
Why is ununoctium referred to as aka-radon?
It has the temporary IUPAC element symbol Uuo. Ununoctium probably shares similar properties of its group, the noble gases, resembling radon in its chemical proerties, and so some some researchers have referred to it as aka-radon . It is probably the second radioactive gaseous element and the first standard semiconcuctive gas.
