History: Discovery was first claimed by scientists at the Nobel Institute in Stockholm in 1957, but their claim could not be verified. In 1958, Albert Ghiorso and colleagues at the Lawrence Berkeley National Laboratory identified a shorter lived isotope.
Where is nobelium found?
In the periodic table, nobelium is located to the right of the actinide mendelevium, to the left of the actinide lawrencium, and below the lanthanide ytterbium.
How was the element nobelium discovered?
In 1957, a group of scientists working at the Nobel Institute of Physics in Stockhlom, Sweden, announced the discovery of a new element. They produced this new element, which they named nobelium, by bombarding a target of curium-244 with ions of carbon-13 with a device called a cyclotron.
Can nobelium be found in nature?
nobelium (No), synthetic chemical element of the actinoid series of the periodic table, atomic number 102. The element was named after Swedish chemist Alfred Nobel. Not occurring in nature, nobelium was first claimed by an international team of scientists working at the Nobel Institute of Physics in Stockholm in 1957.
What is lawrencium used for in everyday life?
Only a few atoms of lawrencium have ever been made. Because of this, there is no commercial use for this element. Its only use is for research within a laboratory. Most actinides are used for their radioactive properties.

Why is nobelium the only actinoid with two oxidation states?
After losing 2 electrons No forms No2+ ion, which is stable due to completely filled 5f-orbitals. iii. Such extra stability due to completely filled orbital is not acquired by any other actinoid in their +2 oxidation state. Hence, nobelium is the only actinoid with a +2 oxidation state.
What is unique about nobelium?
Nobelium (No) has an atomic number of 102, and as such has 102 protons in the nucleus of each of its atoms. It is classified as a metal, but particle sizes prevent it from being seen well enough to identify a color. It is thought to be metallic or silver in appearance.
How many isotopes does nobelium have?
Twelve radioisotopes of nobelium have been characterized, with the most stable being 259No with a half-life of 58 minutes.
Where is lawrencium found in the world?
Source: Lawrencium is a synthetic element and is not found naturally. Lawrencium is created by nuclear bombardment, and has only been produced in miniscule amounts. Lawrencium-256 can be produced by the irradiation of a californium-249 target with boron-11 ions.
How was lawrencium found?
Larsh, Torbjørn Sikkeland and Albert Ghiorso in 1961 at the Lawrence Radiation Laboratory in California. The scientists bombarded 3 mg of californium containing four different isotopes of californium with boron ions in a linear accelerator. From this, several isotopes of lawrencium were obtained.
What's the origin name of lawrencium?
About the Display: Lawrencium is named after Ernest O. Lawrence, who created the cyclotron in 1934. The cyclotron is the first particle accelerator and is the instrument precursor to the large hadron collider.
What does nobelium decay into?
It decays into fermium-255 through alpha decay, into mendelevium-259 through electron capture or through spontaneous fission. Named after Alfred Nobel, inventor of dynamite. Nobelium was unambiguously discovered and identified in April 1958 at Berkeley by A.
What is NH on the periodic table?
nihonium (Nh), also called element 113 or ununtrium, artificially produced transuranium element of atomic number 113.
