2-52. Gallium is a metal with a wide variety of uses, including computer memory chips, light-emitting di- odes, and lasers. Radioactive isotopes of gallium are used to image the human body and locate tumors. Naturally occurring gallium consists of two isotopes. Using the average atomic mass of gallium listed in the periodic table inside the cover of this book, fill in the missing data in the table below. (Hint: Because gallium consists of only two isotopes, what can you conclude about the sum of their abundances?) H (6) 1
