Frequently Asked Questions
How many lanthanide elements are there?
There are 15 lanthanide elements, from Lanthanum (La, atomic number 57) to Lutetium (Lu, atomic number 71).
Why are lanthanides also called rare earth elements?
Historically, lanthanide minerals were thought to be rare. In reality, most lanthanides are fairly abundant — cerium is more common than copper. The name stuck from early chemistry.
Which lanthanide is radioactive?
Promethium (Pm) is the only lanthanide with no stable isotopes. All its isotopes are radioactive, which is why it doesn't occur naturally in significant amounts.
Are lanthanides important for NEET and JEE?
Yes — questions on electronic configuration, oxidation states (+3 is common), and lanthanide contraction appear regularly. Knowing the order and properties gives easy marks.
