How do you find amu of silicon?

Explanation: 27.9768×92.2%+28.9765×4.68%+29.9737×3.10% = 27.9768×0.922+28.9765×0.0468+29.9737×0.0310 = 28.0800 amu .

What are three isotopes of silicon?

isotopes of silicon are known: silicon-28, which makes up 92.21 percent of the element in nature; silicon-29, 4.70 percent; and silicon-30, 3.09 percent. Five radioactive isotopes are known.

Does silicon have any isotopes?

Silicon has nine isotopes, with mass numbers from 25-33. Si (the most abundant isotope, at 92.23%), 29Si (4.67%), and 30Si (3.1%) are stable; 32Si is a radioactive isotope produced by argon decay. Silicon isotopic ratios are compared to the NBS 28 standard for measurement.
