lawrencium उदाहरण वाक्य

उदाहरण वाक्य

1. Chemistry experiments have confirmed that lawrencium behaves as a heavier volatile than expected for its position in the periodic table and have a volatility comparable to that of lead.
2. Further experiments ( Dubna 1969; Berkeley 1970 ) demonstrated an actinide chemistry for the new element, so by 1970 it was known that lawrencium is the last actinide.
3. Most of the chemistry has been observed only for the first three members of the group; chemical properties of both actinium and especially lawrencium are not well-characterized.
4. In the 1950s, 1960s, and 1970s, many claims of the synthesis of lawrencium of varying quality were made from laboratories in the Soviet Union and the United States.
5. Simulations were first run on the Lawrence Berkeley National Laboratory Lawrencium supercomputer to parameterize and benchmark the model against a variety of " in vivo " mammary gland measurements.
6. Californium has also been used to produce other transuranium elements; for example, element 103 ( later named lawrencium ) was first synthesized in 1961 by bombarding californium with boron nuclei.
7. The chemical properties of nobelium and lawrencium were studied with 255 No ( t 1 / 2 = 3 min ) and 256 Lr ( t 1 / 2 = 35 s ).
8. All other known lawrencium isotopes have half-lives under 20 seconds, and the shortest-lived of them ( 252 Lr ) has a half-life of only 390 milliseconds.
9. The Ernest Orlando Lawrence Award was established in his memory in 1959 . Chemical element number 103, discovered at the Lawrence Berkeley National Laboratory in 1961, was named lawrencium after him.
10. In 1961, Ghiorso " et al . " obtained the first isotope of lawrencium by irradiating californium ( mostly californium-252 ) with boron-10 and boron-11 ions.
