The distribution of the magnetic 29Si isotope and silicone oxides (SiO and SiO2) can be correlated because Si oxidation is a spin-dependent process,,, controlled by both external magnetic field and hyperfine interaction. 29 Si prevails in silicon oxidation accelerating this process up to 2 times in comparison with the 28 Si, 30 Si isotopes.
Full Answer
Are 28si and 29Si isotopes?

What is the difference between 24SI and 28SI alternator?
The 28SI provides a much higher amperage output then 24SI Alternators or other competitive brands. It was designed to address vehicle applications that require a larger electrical output but without compromising on weight and fuel savings.
What is the mass of 29Si?
28.9764947Silicon-29 atom is the stable isotope of silicon with relative atomic mass 28.9764947, 4.683 atom percent natural abundancy, and nuclear spin (1)/2.
How many neutrons are in al27?
There are 14 neutrons found in an atom of aluminum-27.
How many neutrons does 29si have?
15 neutronsAnswer and Explanation: There are 15 neutrons.
What is the importance of TMS in NMR spectroscopy?
Tetramethylsilane became the established internal reference compound for 1H NMR because it has a strong, sharp resonance line from its 12 protons, with a chemical shift at low resonance frequency relative to almost all other 1H resonances. Thus, addition of TMS usually does not interfere with other resonances.
What is the abundance of 28si?
92.2%The mass and natural abundance of Si-28 are 27.9769 amu and 92.2%, respectively.
What is 14si?
Silicon (14Si) has 23 known isotopes, with mass numbers ranging from 22 to 44.
What has 13 protons and 14neutrons?
Aluminium-27Answer and Explanation: Hence, the isotope having 13 protons and 14 neutrons is Aluminium-27.
