What is the element Lawrencium as on the Periodic Table?


Definition of the Lawrencium Element
A radioactive transuranic element synthesized from californium. A transuranic element means an element with atoms heavier than those of Uranium with an atomic number greater than 92. Lawrencium does not exist in nature and has very unstable nuclei, so it is are quite hard to make and detect. The Atomic Number of this element is 103 and the Element Symbol is Lr.

Origin / Meaning of the name Lawrencium
Named in honour of Ernest O. Lawrence the inventor of the cyclotron which is a research instrument with which several new elements have been first produced.

 

Periodic Table Group and Classification of the of the Lawrencium Element
Elements can be classified based on their physical states (States of Matter) e.g. gas, solid or liquid. This element is a solid. Lawrencium
classified as an element in the Actinide series as one of the "Rare Earth Elements" which can located in Group 3 elements of the Periodic Table and in the 6th and 7th periods. The Rare Earth Elements are of the Lanthanide and Actinide series. Most of the elements in the Actinide series are synthetic or man-made. Nearly 75% of all the elements in the Periodic Table are classified as metals which are detailed in the List of Metals.

Facts about the Discovery and History of the Lawrencium Element
Lawrencium was discovered by Albert Ghiorso, Torbjorn Sikkeland, Almon Larsh and Robert M. Latimer in 1961 at the Berkeley Radiation Laboratory (now called Lawrence Berkeley National Laboratory) in the University of California.

What is Lawrencium - IUPAC and the Modern Standardised Periodic Table
The Standardised Periodic Table in use today was agreed by the International Union of Pure Applied Chemistry, IUPAC, in 1985 and now recognises more periods and elements than Dimitri  Mendeleev knew in his day in his day but still all fitting into his concept of  the "Periodic Table" in which Lawrencium is just one element that can be found.
