lawrencium उदाहरण वाक्य

Valence 3 is dominant in all subsequent elements up to lawrencium ( with the possible exception of nobelium ).
Long-lived isotopes of nobelium and isotopes of lawrencium ( and of heavier elements ) have relatively short half-lives.
Chemically, scandium, yttrium and lutetium ( and presumably lawrencium ) behave like trivalent versions of the group 1 2 metals.
Such elements include lawrencium, rutherfordium, seaborgium, bohrium, and roentgenium, but not mendelevium, nobelium, or copernicium.
1969 studies on the element showed that lawrencium reacted with chlorine to form a product that was most likely the trichloride LrCl 3.

Since Einsteium and Lawrencium are man made and break down quickly, you could replace them with Technetium and a stick of gum.
In 1965, 18 O . Thus IUPAC recognized the nuclear physics teams at Dubna and Berkeley as the co-discoverers of lawrencium.
However, lawrencium is an exception, since its last electron is transferred to the 7p 1 / 2 subshell due to relativistic effects.
Besides, one of the synthesis reactions for lawrencium, discovered by scientists at Berkeley and Dubna, included bombardment of 243 Am with 18 O.
The half-lives of lawrencium isotopes mostly increase smoothly from 252 Lr to 266 Lr, with a dip from 257 Lr to 259 Lr.
