About carbon dating
So, a carbon atom might have six neutrons, or seven, or possibly eight—but it would always have six protons.An “isotope” is any of several different forms of an element, each having different numbers of neutrons.
The number of neutrons in the nucleus can vary in any given type of atom.
Protons and neutrons make up the center (nucleus) of the atom, and electrons form shells around the nucleus.
The number of protons in the nucleus of an atom determines the element.
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.
