Detailed explanation-4: -Element 103 in the periodic table is called lawrencium. It was first synthesised in 1961 at what was then called the Lawrence Radiation Laboratory, situated close to San Francisco. The synthesis was carried out by a team of scientists led by Albert Ghiorso.

Detailed explanation-5: -Lawrencium (103Lr) is a synthetic element, and thus a standard atomic weight cannot be given. Like all synthetic elements, it has no stable isotopes. The first isotope to be synthesized was 258Lr in 1961. There are fourteen known isotopes from 251Lr to 266Lr, and seven isomers.
