What is Lawrencium?
- 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.
Uses of Lawrencium
- Lawrencium is of not much use due to its radioactive nature.
- They are purely used for scientific research only.
