What is an example of nobelium?
Nobelium is produced for example by bombarding californium with carbon or uranium with neon. The most stable isotope has a half-life of 58 minutes. Most of it decays to fermium or by spontaneous fission.
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.
Is nobelium found in the earth’s crust?
Nobelium doesn’t occur naturally, it has not yet been found in the earth’s crust and it’s so unstable that any amount formed would decompose to other elements very quickly.
How is nobelium made in the universe?
Nobelium is produced via nuclear bombardment of californium-249 or other transuranium atoms with carbon-12 ions in the cyclotron.
Is nobelium ionic or covalent?
Nobelium

How toxic is nobelium?
Nobelium does not occur naturally and because it is unstable, it would quickly decompose to other elements. Thus, it is not considered a health hazard. It is a toxic element due to its radioactivity and has no biological role.
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.
What family does the element nobelium belong to?
Nobelium is solid at room temperature and belongs to the group of actinides. Its density, boiling point, ionic radius, and Vanderwaals radius are unknown. Its 3rd, 2nd, and 1st ionization energies have been measured. The element has two oxidation states (+2 and +3), and its ionization energy is 6.65 eV.
How many isotopes does nobelium have?
Twelve isotopes of nobelium are known, with mass numbers 250–260 and 262; all are radioactive. Additionally, nuclear isomers are known for mass numbers 251, 253, and 254. Of these, the longest-lived isotope is 259No with a half-life of 58 minutes, and the longest-lived isomer is 251mNo with a half-life of 1.7 seconds.
What is the boiling point of nobelium?
Boiling point of Nobelium is –°C. Note that, these points are associated with the standard atmospheric pressure. Boiling Point – Saturation. In thermodynamics, the term saturation defines a condition in which a mixture of vapor and liquid can exist together at a given temperature and pressure.
Who discovered the element nobelium?
Nobelium was discovered by Nobel Institute for Physics and later by Seaborg and others at Berkeley, California, USA in 1958 at Sweden, USA. Origin of name: named after Alfred “Nobel”, Swedish chemist who discovered dynamite, and founder of the Nobel Prizes.
