What is the name of the element in Group 4A and Period 5?
Cerium is the most abundant rare earth metal. Pure cerium ignites when scratched by even a soft object. It has four known isotopes: 136Ce(atomicmass=135.907amu) ,138Ce(atomicmass=137.905amu) ,140Ce(atomicmass=139.905amu), and142Ce(atomicmass=141.909amu). Ce-140 and Ce-142 are fairly abundant. Which is the more abundant isotope?
Mass spectrometric analysis showed that there are four isotopes of an unknown element having the following masses and abundances: Three elements in the periodic table that have atomic weights near these values are lanthanum (La), atomic number 57, atomic weight 138.9055; cerium (Ce), atomic number 58, atomic weight 140.115; and praseodymium (Pr), atomic number 59, atomic weight 140.9076. Using the data above, calculate the atomic weight, and identify the element if possible.
