All members of what family are radioactive?
the actinide series
What family is all radioactive elements?
The Actinide series.
What are the example of radioisotopes?
Hydrogen-3 Carbon-14 Potassium-40 All isotopes every Actinide (eg=Uranium, Actinium, Thorium) All isotopes of Technetium , etc.
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 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
Are all actinids radioactive?
There are a total of 15 actinides in the actinide series and each are chemical elements with metallic properties. All of the actinide elements are radioactive and upon radioactive decay they release energy.
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.
What is the name of two series of inner Transition elements?
The lanthanide and actinide series. Trait of lanthanide: Lanthanum, element 57. Trait of actinide: actinium, element 89.
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.
