lawrencium वाक्य

उदाहरण वाक्य

1. Valence 3 is dominant in all subsequent elements up to lawrencium ( with the possible exception of nobelium ).
2. Long-lived isotopes of nobelium and isotopes of lawrencium ( and of heavier elements ) have relatively short half-lives.
3. Chemically, scandium, yttrium and lutetium ( and presumably lawrencium ) behave like trivalent versions of the group 1 2 metals.
4. Such elements include lawrencium, rutherfordium, seaborgium, bohrium, and roentgenium, but not mendelevium, nobelium, or copernicium.
5. 1969 studies on the element showed that lawrencium reacted with chlorine to form a product that was most likely the trichloride LrCl 3.
6. Since Einsteium and Lawrencium are man made and break down quickly, you could replace them with Technetium and a stick of gum.
7. In 1965, 18 O . Thus IUPAC recognized the nuclear physics teams at Dubna and Berkeley as the co-discoverers of lawrencium.
8. However, lawrencium is an exception, since its last electron is transferred to the 7p 1 / 2 subshell due to relativistic effects.
9. Besides, one of the synthesis reactions for lawrencium, discovered by scientists at Berkeley and Dubna, included bombardment of 243 Am with 18 O.
10. The half-lives of lawrencium isotopes mostly increase smoothly from 252 Lr to 266 Lr, with a dip from 257 Lr to 259 Lr.
