Chemical Properties of Lawrencium

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 synthesised from californium.

Uses of Lawrencium

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