<span>Plate tectonics is the theory that the earth's crust is broken up into plates
that float on top of a hotter and more fluid layer below. Evidence to
support this theory has been uncovered through the study of the earth's
past magnetic field, known as paleomagnetism.</span>
Hello,
The mass number is protons+neutrons=mass number. In this case, we have protons+nuetron=164.The atomic number is simply the number of protons so we have 43+neutrons=164. Subtracting 43 from both sides we get nuetrons=121. Hope this helps!
