What family is made up of all radioactive elements?
The actinides
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.
What are the unique properties of actinide metals?
They are mostly Synthetic elements (when nuclear particles are forced to crash into one another by a particle accelerator (machine)). These Elements are Radioactive.
Are halogens more reactive than actinides?
No actinides are more reactive
Where are landthanides and actinides actinides placed in the periodic table?
Lanthanides and Actinides are placed separately as the properties of these elements is quite different from the elements in periodic table.
Are all atoms of actinides radioactive?
Yes. All of the actinides are radioactive.
Is a characteristic of Actinides?
All actinides are radioactive elements and some are man made.
Is a characteristic of the actinides?
All actinides are radioactive elements and some are man made.
What are all but 3 actinides?
radioactive
What property of actinides makes americium useful in smoke detectors?
Radioactive elements are able to ionize the air.
What was the first of all the actinides?
Thorium (90)
What is the physical property of Lawrencium?
Lawrencium is a synthetically prepared element, a metal, has an atomic mas of 103, and is one of the Actinides.
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 are hazards in actinides?
importance abuot actinides
What family is Americium in?
Americium is and actinide.
