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.
What are the properties of lanthanides and actinides?
The lanthanides and actinides are part of the inner transition metals. Actinides are all radioactive, highly electropositive and tarnish readily in air. Lanthanides burn easily in air, have high melting and boiling points and are strong reducing agents.
Are most of the actinides occur naturally in earth's crust?
No, most of the actinides do not occur naturally in Earth's crust. Actinides are a group of elements that are mostly synthetic or man-made through nuclear reactions. Only a few actinides, like uranium and thorium, occur naturally in significant quantities in the Earth's crust.
What are the unique properties of actinide metals?
Actinide metals have unique properties including high density, high melting points, and the ability to exhibit multiple oxidation states. They are also radioactive and can undergo fission, making them important for nuclear power generation and weapons production. Additionally, actinides have a variety of magnetic and electronic properties that make them useful in various technological applications.
Are halogens more reactive than actinides?
Halogens are generally more reactive than actinides. Halogens are a group of elements known for their high reactivity due to their ability to easily gain an electron and form negative ions. Actinides, on the other hand, are a series of radioactive elements that tend to be less reactive overall.
Are all atoms of actinides radioactive?
Yes. All of the actinides are radioactive.
Is a characteristic of the actinides?
All actinides are radioactive elements and some are man made.
Is a characteristic of Actinides?
All actinides are radioactive elements and some are man made.
What are all but 3 actinides?
radioactive
What was the first of all the actinides?
Thorium (90)
What property of actinides makes americium useful in smoke detectors?
Radioactive elements are able to ionize the air.
What is made up of all radioactive elements?
The actinides
Who named actinides as 'actinides'?
mosley
Why are the nuclear structures of the actinides more important than the electron configuration's of the actinides?
Because the nuclei of actinides are unstable and spontaneously break apart, all actinides are radioactive.
What do the lanthanide and actinides all have in common?
They are F-block elements
Is plutonium a non metal?
No, it is a metal, as all the other actinides are.
What are hazards in actinides?
importance abuot actinides
