Lawrencium (Lr) - Periodic Table
网页Lawrencium was discovered by Albert Ghiorso, Torbjørn Sikkeland, Almon Larsh and Robert M. Latimer in 1961 at the University of California, Berkeley. It was produced by the bombardment of californium with boron atoms. Lawrencium was the last member of the actinide series to be discovered. Named after Ernest O. Lawrence, inventor of the cyclotron

网页Mass Number. The sum of the number of protons and neutrons of an atomic nucleus. In other words, it's the sum of the number of nucleons in an atom. Relative Atomic Mass. The ratio of the average mass per atom of an isotope to 1/12 the mass of a carbon-12 atom. Relative atomic mass is also known as atomic weight (symbol: A r).

网页2024年2月28日 · Most lawrencium isotopes decay by emitting alpha particles. The lightest isotopes of lawrencium, lawrencium-251 to lawrencium-254, are produced as alpha decay products of dubnium.
Lawrencium (Lr) - Definition, Preparation, Properties, Uses
网页2024年4月27日 · Lawrencium is a synthetic element with the chemical symbol Lr and atomic number 103. It is produced in particle accelerators through the bombardment of lighter atomic nuclei. Like nobelium, lawrencium does not exist naturally and is known for its extremely short half-life, which limits the opportunity for detailed study.

网页They are unstable and unnatural [3]. The most stable isotope is lawrencium-266 that has a half-life of eleven hours. Lawrenium-260 has a half-life of around three minutes and is widely used in laboratory experiments as it is easily produced. Most of the isotope of lawrencium undergo decay through emission of alpha particles. REFERENCES [1].
Lawrencium | Periodic Table
网页Lawrencium's most stable isotope, lawrencium-262, has a half-life of about 4 hours. It decays into nobelium-262 through electron capture, mendelevium-258 through alpha decay or through spontaneous fission. Since only tiny amounts of lawrencium have ever been produced, there are currently no uses for it outside of basic scientific research.
