Question

(DO THIS ONE NOT THE OTHER) The element Chromium has 4 naturally occurring isotopes. Use the relative abundance of each to calculate the average atomic mass of chromium. (Must show work!)

Cr-50 = 4.34%, Cr-52 = 83.79%, Cr-53 = 9.50%, Cr-54 = 2.37%

Answer 1

The average atomic mass of Chromium is 52.0556. The electronic configuration of Chloride ion is [tex]\rm 1s^2\;2s^2\;2p^6\;3s^2…
