I dunnu, I googled the same thing. This guys notes says "A group of elements in the first row of the rare earth elementsin the Periodic Table"
What else can I help you with?
Are lanthinides reactive?
Yes they are but less than Actinoids.
Do lanthinides contain radioactive elements?
Yes, promethium, which is a lanthanide, has no stable isotopes.
Who named actinides as 'actinides'?
mosley
What are hazards in actinides?
importance abuot actinides
Are all atoms of actinides radioactive?
Yes. All of the actinides are radioactive.
What the characteristics of actinides?
actinides are the group of elements in the periodic table,see..........
What is the difference between lanthanides and actinides?
Wht is the difference between Lanthanides and Actinides?
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.
Do actinides and lanthanides lose electrons when combining?
Actinides and lanthanides lose electrons and form cations.
What family is Americium in?
Americium is in the Actinide family of elements. It is a synthetic element with the symbol Am and atomic number 95. Actinides are a series of elements in the periodic table that have properties similar to actinium.
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.
