This 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.

The lightest naturally occurring actinide on Earth is thorium, which has the atomic number 90. It is a naturally occurring radioactive element found in small amounts in soil and rocks.
What is the element for the symbol No?
The element for the symbol No is Nobelium. It is a radioactive metal that belongs to the actinide series of the periodic table.
What is the name of any element of the actinide series which have atomic numbers from 89 actinium Ac through 103 lawerencium Lr?

Is actinide considered a synthetic element?
Actinide is not an element, but is a series of elements. Of the actinide series of elements, all except actinium, thorium, protactinium, and uranium are considered to be synthetic elements because they are not found in nature in appreciable amounts.

URANIUM (:
What element is the heaviest actinide that occurs natrually on earth?
Uranium
What is the first element of the actinides?
The first element in the actinide series is actinium , a chemical element in the periodic table that has the symbol Ac and atomic number 89.The actinide (or actinoid) series encompasses the 15 chemical elements that lie between actinium and lawrencium on the periodic table , with atomic numbers 89-103.The actinides get their name from the first element in the series , actinium.
What element is the actinide named for the creator of the Periodic Table?
The element that is an actinide and named for the creator of the periodic table is Mendelevium (Md). Mendelevium has atomic number 101 and is named after Dmitri Ivanovich Mendeleev.
Where is thorium located on the periodic table?
The atomic number of thorium, Th, is 90 and it is an inner transition element in the Actinide series. The Actinide series is the second of the two series shown by themselves. It starts Actinium, Thorium, Protactinium, and Uranium, so Thorium is the second element in the Actinide series.
Which element group does Uranium belong to?
Uranium belongs to the actinide group of elements.
