Roentgenium-272 has 161 neutrons.
Number of neutrons = Atomic Mass of an isotope - Atomic number of the element
The atomic number of roentgenium is 111, but Rg has many isotopes each with a different atomic mass and number of electrons.
For each isotope of Rg the number of neutrons is different.Number of neutrons = Mass number of an Rg isotope - 111
Roentgenium is a highly radioactive element that does not exist naturally and is only produced in laboratories. Due to its short half-life and high radioactivity, roentgenium is considered very dangerous. Handling even small amounts of roentgenium poses significant health risks.
It is supposed that the chemical properties of roentgenium are similar to the properties of silver.
Roentgenium (also called unununium) is classified in the metals.
The electron configuration of roentgenium is: [Rn]5f14.6d9.7s2.
Roentgenium (Rg) has 111 protons and an atomic mass of approximately 282 u. Since atomic mass - atomic number = number of neutrons, Roentgenium is estimated to have around 171 neutrons. In a neutral atom of Roentgenium, the number of electrons would also be 111.
For each isotope of Rg the number of neutrons is different.Number of neutrons = Mass number of an Rg isotope - 111
