Atomic number of Cr is 24. Atomic Mass (amu) Atomic Mass (amu) In nature, most elements occur as mixture of one or two isotopes. Each isotope has a fixed mass and natural percent abundance. Consider three isotopes of Hydrogen Hydrogen 1 (99.985%) Hydrogen 2 and 3 present in trace amoun...
number of neutrons, and hence in their atomic mass.The isotopes of a given element have the same chemical properties but slightly different physical properties.We now know that atomic number (the number of protons in the nucleus), not atomic mass number (the number of protons and neutrons), ...
2. Boron has two naturally occurring isotopes. Find the percent abundances of10B and11B given the isotopic mass of10B = 10.0129 amu and the isotopic mass of11B = 11.0093 amu. 3. Chlorine has two naturally occurring isotopes,35Cl (34.9689 amu) and37Cl (36.9659 amu). If chlorine has an av...
