Is manganese a representative element

Answer 1

Manganese is not a rare earth element. The rare earths range from Lanthanum (atomic number 57) to Hafnium (70) and Actinium (89) to Rutherfordium (102). Manganese is atomic number 25. Looking at the Periodic Table, you will see two rows at the bottom named Lanthanoids and Actinoids - those are the rare earths.

No. The rare earth elements are scandium, yttrium and the Lanthanides, which have atomic numbers ranging from 57 to 70 (lanthanum, neodymium, samarium, etc.). The atomic number for iron is 26.
