- Lawrencium with atomic number 103 is represented in the periodic table with the symbol ‘Lr’
- It never occurs as a free element in nature it was created by accelerating sub-atomic particles that have been surrounded by a circle. So that there is sufficient energy to destroy an existing atom and create a new atom.
- Lawrencium is a radioactive transuranic element that is synthesized from californium.
- Lawrencium is of not much use due to its radioactive nature.
- They are purely used for scientific research only.
- Lawrencium is of not much use. They are purely used for scientific research only.
- Isotopes of Lawrencium are radioactive. Its isotopes have a half-life of eleven hours and it is the longest-lived super-heavy till date.
- Among all isotopes of Lawrencium, only 12 isotopes are known with mass numbers 252, 262 and 266.
- It was discovered in the year 1961, on February 1991.
- It is actually an actinide in spite of its position in the periodic table that should be a transition metal.
