Here's a list of the chemical elements ordered by increasing atomic number. The names and element symbols are provided. Each element has a one- or two-letter symbol, which is an abbreviated form of its present o
(LREEs). Elements with high atomic weight are the heavy rare earth elements (HREEs). Elements that fall between the two extremes are the middle rare earth elements (MREEs). One popular system categorizes atomic numbers up to 61 as LREEs and those higher than 62 as HREEs (with the ...
