Chromium is a metal, which is an important ingredient in the preparation of stainless steel, an alloy widely used in our daily lives from household gadgets to huge machineries. Chromium provides corrosion resistance to stainless steel and prevents rusting. Chromium exists in four main isotopes, which have atomic masses as given below:
Cr-50 with atomic Mass of 49.9460442 amu
Cr-52 with atomic Mass of 51.9405075 amu
Cr-53 with atomic Mass of 52.9406494 amu
Cr-54 with atomic Mass of 53.9388804 amu
If the average atomic mass of chromium is 51.996 amu, Which isotope do you think is the most abundant isotope?
