Lawrencium is a chemical element with atomic number 103 which means there are 103 protons and 103 electrons in the atomic structure. Isotopes of Lawrencium are radioactive. Properties of Lawrencium. The isotopes of lawrencium decay via alpha emission, spontaneous fission and electron capture (in order of most to least common types). Atomic weight of known its 11 isotopes range from 252 to 262. There are eleven isotopes of lawrencium, and one isomer. They are purely used for scientific research only. In the periodic table, Lawrencium behaves as a heavier homolog to lutetium and is a trivalent element that chemistry experiments have confirmed. Physical Properties. The chemical symbol for Lawrencium is Lr.. Lawrencium is the final member of the actinide series. It is chemically similar to other actinides, and is homologous to lutetium. If sufficient amounts of lawrencium were produced, it would pose a radiation hazard.

Lawrencium is the second transferium element with the most stable isotope 262 Lr having a half-life of 216 minutes. Its isotopes have a half-life of eleven hours and it is the longest-lived super-heavy till date. Lawrencium is the final member of the actinide series and is sometimes considered to be a group 3 element, along with scandium, yttrium, and lutetium, as its filled f-shell is expected to make it resemble the 7th-period transition metals. Lawrencium is a chemical element with atomic number 103 which means there are 103 protons in its nucleus.Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z.The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs. It's chemical data are limited to its atomic number, its haf life and isotopes. It is the last element found in the actinide series, and is also the heaviest.
