The atomic number corresponds to the number of protons in an atom.
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.

God knows just what He meant to say, and His understanding of science is infallible, whereas ours is fallible.
So we should never think it necessary to modify His Word.
(The electrons are so much lighter that they do not contribute significantly to the mass of an atom.) C), also referred to as radiocarbon, is claimed to be a reliable dating method for determining the age of fossils up to 50,000 to 60,000 years.
