Recall that atoms are the basic building blocks of matter.Atoms are made up of much smaller particles called protons, neutrons, and electrons.Scientists use a technique called radiometric dating to estimate the ages of rocks, fossils, and the earth.
The cosmic-ray flux, and hence the production rate of C-14, is a function not only of the solar activity but also of the magnetic dipole moment of the Earth.4Though complex, this history of the earth’s magnetic field agrees with Barnes’ basic hypothesis, that the field has always freely decayed....The atomic number corresponds to the number of protons in an atom.Atomic mass is a combination of the number of protons and neutrons in the nucleus.The procedures used are not necessarily in question. The secular (evolutionary) worldview interprets the universe and world to be billions of years old. The use of carbon-14 dating is often misunderstood.
Carbon-14 is mostly used to date once-living things (organic material). Carbon-14 is constantly being added to the atmosphere.
Protons and neutrons make up the center (nucleus) of the atom, and electrons form shells around the nucleus.
