Subatomic Particles Practice Sheet Fill in the blanks in the following sheet. Please keep in mind that the isotope represented by each space may NOT be the one closest to the atomic mass in the periodic table (ie. don't use the periodic table to find masses). If you have problems, the second page of this sheet will include tips for solving problems like these (but not answers), with the answers themselves provided on page 3.

These are just two different isotopes of Yb, so the number of neutrons and the atomic mass are different.
