Beryllium dating

All beryllium atoms have four protons but could have between one and ten neutrons.

There are ten known isotopes of beryllium, ranging from Be-5 to Be-14.

Upon reaching the earth’s surface, a small percentage of carbon-14 containing carbon dioxide is taken up by plants and then incorporation into plant biomolecules via photosynthesis.

It becomes incorporated into the biomolecules of heterotrophic organisms (animals) via the food chain.

(Remember, various ancient peoples were known to be expert seamen, and for this phrase to refer to the entire world, and for Egypt to feed the entire world, was not a huge logistical impossibility. But they also had more than just ships to get around in too. The Earth shook, scorched by the terrible heat of this weapon.

Here is a collection of reader-submitted chemistry jokes and puns.

Some of them are groaners, but some are quite funny.

The radiocarbon dating method is based on the fact that plant and animal tissue levels of carbon-14 remain relatively constant during life, but taper off at a predictable rate in surviving remains. Typically, traces of radiocarbon can be detected in organic remains up to 50,000 years old.

You don't hear a lot of jokes, puns, or riddles in physics and biology, but chemistry is full of them.
