Interesting facts about radioactive dating

But a study published in May posits that Alexander got assistance from a submerged sandbar, so he crossed water only a yard or two deep.

This molecule turned out to be a soccer-ball-shaped sphere made of 60 carbon atoms.Carbon-14 is a radioactive isotope of carbon used by archaeologists to date objects and remains.Carbon-14 is naturally occurring in the atmosphere.There is no shortage of stories about Alexander the Great’s military accomplishments. History tells us that Alexander, after laying siege to the massive fort for seven months, made his final assault by having his engineers build a half-mile causeway connecting the island to the mainland–a stunning feat. conquering of the seemingly impenetrable Phoenician island fortress of Tyre, was revised a bit this year.This method works on once-living organisms, including objects made of wood or other plant material.

Carbon is a long-studied element, but that doesn't mean there isn't more to discover.

It’s always fascinating when archaeology and other forms of science can be applied to the historical record.

In this case, geoarchaeology explains not only how Alexander made his assault, but also how he actually reshaped Lebanon’s coastline.

Under very hot temperatures — greater than 100,000,000 Kelvin (179,999,540.6 F) — the helium nuclei begin to fuse, first as pairs into unstable 4-proton beryllium nuclei, and eventually, as enough beryllium nuclei blink into existence, into a beryllium plus a helium.

The end result: Atoms with six protons and six neutrons — carbon.

Carbon has four empty spaces in its outer shell, enabling it to bond to four other atoms.
