Which of the following elements tend to be radioactive?
Ra and Ac Pu and Th Am and U
What is the radioactive element in period 5?
The radioactive element in period 5 of the periodic table is Actinium (Ac). It is a radioactive metal with atomic number 89.
What is the first actinide element?
ActinidesThis is a group of elements within the periodic table and are also known as the transuranics. The name refers to those elements with increasing atomic no. from actinium, which all have similar chemical properties, like the lanthanides. The first few members of the group are the naturally occurring elements actinium, thorium, proactinium and uranium. Beyond this elements have been made artificially by radioactive bombardment. These artificial elements are unstable, some have very short lifeimes and undergo spontaneous radioactive decay.
Which element has the following configuration 6s24f75d1?
The element with the electron configuration 6s2 4f7 5d1 is Actinium (Ac) with atomic number 89.
What is the name of the elements with atomic numbers 90 through 103?
The elements are called Actinides. They are placed at the bottom of periodic table. These elements have different properties.These elements are in the f group of the periodic table. Elements from Ac-Lr belong to this group. These are called Actinides.
Is ac radioactive?
Actinium is radioactive. The Ac-227 isotope has a half life of 21.77 years
Where is acinium found?
Actinium is separated from pitchblende. Actinium, AC, is found in uranium ore, a product of radioactive decay of uranium and ?æother unstable elements.
Is actinium a family name or rare earth element series?
Actinium (Ac) is a chemical element.Actinoids is the name of the radioactive elements family which contain actinium.
What is the meaning of actinium?
Actinium is a radioactive element with symbol Ac.
What is the eighty ninth element in the periodic table of the elements?

What are the atomic numbers 81-100?
Elements 89-100 are the Actinide series of elements, most of which are radioactive, and some of which can only be made artificially. Elements 81-88 are also likely to be radioactive, but are naturally occurring.
Why there is phase shift in AC circuit?
due to presence of passive elements
What transition elements are called lanthanides and acttinides?
Elements La(Lanthanum)-Lu(Lutetium) are the lanthanides. Elements Ac(Actinium)-Lr(Lawrencium) are the actinides.
