What is the average atomic mass of Si if 92.21% of its atoms have mass 28 amu, 4.70% of its atoms have mass 29 amu, and 3.09% of its atoms have mass 30
amu?

100%sorry if i’m wronghope this good luck: )

Green is technically every other color but green but the other wavelengths of the other colors get absorbed by the object and the wavelength of the color green gets reflected

Ithink the answer is c

Most elements have more than one naturally occurring isotope. as you learned previously, the atoms of those isotopes have the same atomic number (number of protons), making them belong to the same element, but they have different mass numbers (total number of protons and neutrons) giving them different atomic masses. so which mass is put on the periodic table for each element? is it the most common isotope’s mass? the heaviest mass? this activity will answer that question.
