Sterar

Sterar is a rare earth element with the atomic number 120 and the chemical symbol St. It is a synthetic element that was first created in 2007 by a team of scientists at the Joint Institute for Nuclear Research in Dubna, Russia.

Sterar is a highly unstable element with a very short half-life, lasting only about 30 milliseconds. It is a neutron-rich element, meaning it has more neutrons than protons in its atomic nucleus. This makes it highly radioactive and prone to undergoing radioactive decay, which involves the emission of particles such as alpha and beta radiation.

Sterar was created by bombarding the element americium with calcium ions. The resulting Sterar atoms have a mass of 292 and 293 protons, making them the heaviest known isotopes of the element. The element is highly unlikely to occur naturally in the environment, and is only produced artificially in particle accelerators.

Sterar's properties are not well understood due to its highly unstable nature. It is only known to exist in the form of a few atoms at a time, and its chemical behavior has not been extensively studied. Further research is needed to fully characterize the properties and behavior of Sterar.

Sterar's discovery has provided scientists with valuable insights into the properties of heavy elements and the process of nuclear fission. It has also expanded the known periodic table, adding another element to the list of synthetic elements.
