How reactive are lanthanides and actinides metals?
lanthanides and actinides are fairly reactive, but not as much as say, the alkali metals in group 1
What series are called elements 57 to 70?
Elements from atomic number 57 (Lanthanum) to 71 (Lutetium) are called the Lanthanides. Lanthanide means "like Lanthanum" and so, the Lanthanides are based on Lanthanum. Only one of the Lanthanides is radioactive: Promethium (Pm - No. 61)
What are the 2 words that describe the classification of the 17 chemical elements with the numbers 57-71?

What is the major difference between lanthanides and actinides?
Generally speaking, the lanthanides are naturally occurring and stable, although relatively uncommon. The actinides are naturally occurring through uranium; after that, they're synthetic, and all are unstable (radioactive.)
Do actinides and lanthanides lose electrons when combining?
Actinides and lanthanides lose electrons and form cations.
What elements on the periodic table is a radioactive element?
Lanthanides and Actinides probably
A major difference between the two rows of inner transition elements is that the lanthanides?
are radioactive and the actinides are not
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 Lanthanides and Actinides?
Elements. The Lanthanides are: Atomic No.575859606162636465666768697071NameLaCePrNdPmSmEuGdTbDyHoErTmYbLu The Actinides are:Atomic No.8990919293949596979899100101102103NameAcThPaUNpPuAmCmBkCfEsFmMdNoLr
What is the first actinide element?
ActinidesThis is a group of elements within the periodic table and are also known as the transuranics. The name refers to those elements with increasing atomic no. from actinium, which all have similar chemical properties, like the lanthanides. The first few members of the group are the naturally occurring elements actinium, thorium, proactinium and uranium. Beyond this elements have been made artificially by radioactive bombardment. These artificial elements are unstable, some have very short lifeimes and undergo spontaneous radioactive decay.
What is the difference between lanthanides and actinides?
Wht is the difference between Lanthanides and Actinides?
What are the elements of 4F series called?
The 4f series is referred to as the Lanthanides.
What about the complex formation ability of lanthanides as campared to actinides?
describe the complex formation by lanthanides?
What section of the periodic table is the 4f subshell being filled?
Atoms first occupy the 4f level in the Lanthanide series, beginning with Cerium (Ce).
