The actinides all have a numerical ratio of protons to neutrons that makes their atomic nuclei unstable. This causes those nuclei to expel some type of particle (alpha or beta) and this causes a transmutation into another less massive (and usually more stable) element. This is radioactive decay.
What else can I help you with?
Is a characteristic of the actinides?
All actinides are radioactive elements and some are man made.
Are lanthanides radioactive?
Some lanthanides are radioactive, such as promethium. However, most lanthanides found in nature are stable.
What is the name of the series which contains most of the synthetic and radioactive elements?
All of the actinides are radioactive, and almost all are synthetic.
What are the characteristics for actinides?
radioactive
Why are actinides radioactive?
Actinides are radioactive because they have unstable atomic nuclei that tend to undergo nuclear decay by emitting radiation in the form of alpha, beta, or gamma rays. This radioactive decay process results in the transformation of actinides into other elements, often leading to the formation of stable isotopes over time.
Are all atoms of actinides radioactive?
Yes. All of the actinides are radioactive.
What are all but 3 actinides?
radioactive
Is a characteristic of Actinides?
All actinides are radioactive elements and some are man made.
Is a characteristic of the actinides?

Are lanthanides radioactive?
Some lanthanides are radioactive, such as promethium. However, most lanthanides found in nature are stable.
What is made up of all radioactive elements?
The actinides
What family is made up of all radioactive elements?
The family of radioactive elements is called the Actinides. This group includes elements such as uranium, thorium, and plutonium, which are known for their radioactive properties.
A property of all actinides is that they are all what?
Actinoids are: Th, Pa, U, Np, Am, Cm, Bk, Cf, Es, Fm, Md, No, Lr.
What is the name of the series which contains most of the synthetic and radioactive elements?
All of the actinides are radioactive, and almost all are synthetic.
What are the characteristics for actinides?
radioactive
Family characteristic actinides have?
All are radioactive and all of them can show the oxidation state of +3
All of the actinides are?
radioactive elements that belong to the periodic table group of actinides. They have increasing atomic numbers starting from actinium (Z=89) to lawrencium (Z=103). Actinides are often used in nuclear reactors and are known for their radioactive properties.
