Problem # 3b: Naturally occurring silicon consists of 3 isotopes, Si-28, Si-29 and Si-30, whose
atomic masses are 27.9769, 28.9765 and 29.9738 respectively. The most abundant isotope is
Si-28 which accounts for 92.23% of naturally occurring silicon. Given that the observed atomic
mass of silicon is 28.0855 calculate the percentages of Si-29 and Si-30 in nature.

For example, an atom with 47 protons is always a silver atom and has an atomic number of 47. The atomic number is used to distinguish different elements from one another. The mass number A is the sum of the number of protons and neutrons in the nucleus of an atom of an element. Atoms that have the same atomic number but different mass numbers are called isotopes. For example, all atoms with atomic number 6 are carbon atoms, but carbon atoms with mass numbers of 12 and 13 are isotopes of one another. Each element is assigned a unique chemical symbol. For example, the symbol for hydrogen is H, and the symbol for oxygen…arrow_forward
