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.
What inner transition metal has 90 electrons?
Thorium (Th) is an inner transition metal with 90 electrons. It is a radioactive element that belongs to the actinide series of the periodic table.
What family does fermium belong to?
Fermium is a member of the actinides group.
What is the name of any element of the actinide series which have atomic numbers from 89 actinium Ac through 103 lawerencium Lr?
One element in the actinide series is thorium (Th), which has an atomic number of 90.
Lowest atomic number actinide?
Hydrogen is a none metal element. atomic number of it is 1.
Is actinide considered a synthetic element?

What family is ferium in?
The actinide series.
Is the actinide series soft metals?
No uranium is an actinide and is very hard especially depleted uranium
What family is radioactive elements?
The Actinide series.
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.
All members of what family are radioactive?
the actinide series
What family is all radioactive elements?
The Actinide series.
What are the series of inner transitions elements and what is a trait of each?
The lanthanide and actinide series. Trait of lanthanide: Lanthanum, element 57. Trait of actinide: actinium, element 89.
What are the two series of inner transition elements and what is the trait of each?
The lanthanide and actinide series. Trait of lanthanide: Lanthanum, element 57. Trait of actinide: actinium, element 89.
What are the two metal groups?
the two groups of metals is the Lanthanide series and the Actinide series.
The lanthanied actinide series make up the inner transition metals true or false?
True. The lanthanide and actinide series make up the inner transition metals. The lanthanide series includes elements with atomic numbers 57-71 (lanthanides), while the actinide series includes elements with atomic numbers 89-103 (actinides).
Which block on the periodic table contains the actinide series of elements?
The actinide series of elements can be found in the f-block of the periodic table, specifically in the 7th row. These elements are known for their radioactive properties and include well-known elements such as uranium and plutonium.
