=<span style="color: black; font-family: 'Arial','sans-serif'; font-size: 22pt; mso-bidi-font-weight: bold; mso-fareast-font-family: 'Times New Roman';">The element <span style="color: black; font-family: 'Arial','sans-serif'; font-size: 22pt;">Lawrencium was created by four American scientists, Albert Ghiorso, Torbjorn Sikkeland, Almon E. Larsh and Robert M. Latimer, in 1961. It is synthesized by the element Californium. = = = <span style="color: black; font-family: 'Arial','sans-serif'; font-size: 24pt; line-height: 115%;">Lawrencium is the second transferium element with the most stable isotope 262 Lr having a half-life. <span style="color: black; font-family: 'Arial','sans-serif'; font-size: 24pt; line-height: 115%; mso-ansi-language: EN-US; mso-bidi-language: AR-SA; mso-fareast-font-family: Calibri; mso-fareast-language: EN-US; mso-fareast-theme-font: minor-latin;">The isotope that has half-life last for 216 minutes.

<span style="font-family: 'Arial','sans-serif'; font-size: 26pt; line-height: 115%;"> Lawrencium was named in honor after Ernest Lawrence. He was the inventor of the cyclotron.
