See all on Wikipediahttps://en.wikipedia.org/wiki/ActinideThe actinide or actinoid (/ˈæktɪnɔɪd/) series encompasses the 15 metallic chemical elements with atomic numbers from 89 to 103, actinium through lawrencium. The actinide series derives its name from the first element in the series, actinium. The informal chemical symbol An is used in general discussions of … See more
Like the lanthanides, the actinides form a family of elements with similar properties. Within the actinides, there are two overlapping groups: transuranium elements, which follow uranium in the periodic table; … See more
The figure buildup of actinides is a table of nuclides with the number of neutrons on the horizontal axis (isotopes) and the number of protons on the vertical axis (elements). The red dot divides the nuclides in two groups, so the figure is more compact. … See more
32 isotopes of actinium and eight excited isomeric states of some of its nuclides were identified by 2016. Three isotopes, Ac, Ac and Ac, were found in nature and the others were … See more

Actinide chemistry (or actinoid chemistry) is one of the main branches of nuclear chemistry that investigates the processes and molecular systems of the actinides. The actinides derive their name from the group 3 element actinium. The informal chemical symbol An is used in general discussions of actinide chemistry to refer to any actinide. All but one of the actinides are f-block elemen…

Toate au 86 de electroni distribuiți precum în gazul nobil radon și trei electroni adiționali care pot fi poziționați în orbitali 6d sau 7s (în exterior). Fiecare electron adițional ocupă apoi orbitalii interiori, ceea ce conduce la fenomenul de contracție a actinidelor (simila…
