series encompasses the 15 metallic chemical element s with atomic number s from 89 to 103, actinium through
lawrencium The actinide series
Kaynak: Actinide(La) and actinium (Ac), or by lutetium (Lu) and
lawrencium (Lr); less frequently, it is considered the group should be expanded to 32
Kaynak: Group 3 element(either lanthanum or lutetium, and either actinium or
lawrencium , respectively) shown in a single cell of the main table, between barium
Kaynak: Periodic tablealpha decay of 260 Db with a half-life of 1.6 seconds and a decay energy of 9.10 MeV, correlated with the daughter decay of
lawrencium -256:
Kaynak: DubniumAlthough lutetium and
lawrencium are in the d-block, they are not considered transition metals but a lanthanide and an actinide ,
Kaynak: D-blocktransuranium elements; for example, element 103 (later named
lawrencium ) was first synthesized in 1961 by bombarding californium with boron nuclei

Kaynak: Ernest Lawrenceelements with odd atomic numbers: mendelevium and
lawrencium , and also some of the transactinide very-heavy elements, such as rutherfordium .
Kaynak: Spontaneous fissionActinium gave the name to the actinide series, a group of 15 similar elements between actinium and
lawrencium in the periodic table .
Kaynak: Actiniumheavy elements) are the chemical element s with atomic number s greater than those of the actinide s, the heaviest of which is
lawrencium (103
Kaynak: Transactinide elementThe elements are also known as inner transition elements, although that term is normally taken to include lutetium and
lawrencium as
