1.) why aren't the atomic masses of most elements whole numbers?
2.) Magnesium has three naturally occurring isotopes 24Mg, 25Mg, and 26Mg. What is the mass number of each isotope? How many protons, neutrons, and electrons are present in each?
3.) Gallium has two naturally occuring isotopes, 69Ga (isotopic mass 68.9689 amu, abundance 60.11%) and 71Ga (isotopic mass 70.9247 amu, abundance 39.89%). Calculate the atomic mass of Gallium
4.) Chlorine has two naturally occurring isotopes, 35Cl (isotopic mass 34.9689 amu) and 37Cl (isotopic mass 36.9659 amu). If chlorine has an atomic mass of 35.4527 amu, what is the percent abundance of each chlorine isotope?
