Since protons and neutrons weigh about the same, the atomic mass of ordinary carbon is 6 6 = 12.
It is called “Carbon-12,” which is abbreviated “C.” The fact that the atom has six protons is what makes it carbon.

"Every year the trees in our forests show the swing of Time's pendulum and put down a mark.
They are chronographs, recording clocks, by which the succeeding seasons are set down through definite imprints," he wrote in the pages of National Geographic.
Due to the sweeping and diverse applications of this data, specialists can come from many academic disciplines.
There are no degrees in dendrochronology because though it is useful across the board, the method itself is fairly limited.
In its most conventional form, dendrochronology works like this. They have no bias, and they have no political agenda; they just stand at locations all over the world," says Charlotte Pearson, an assistant professor of dendrochronology at the UA, studies samples under a microscope.
A contemporary tree—that is, a tree that was either just cut down or still living—can tell you not just how many years it has lived, but which years in which it lived. Credit: credit: Mari Cleven But what if the wood is older?
If a Bigtooth Maple were cut down on Mount Lemmon in 2016 and it had 400 rings, you would know the tree started growing in 1616. What if it's been used to build a home or a ship or a bonfire?
The rings could still tell how many years the tree lived, but not necessarily when. He set out on a series of expeditions across the southwest to bridge the gap between contemporary wood and wood beams from the ruins of civilizations long gone.
About 21 pounds of Nitrogen is converted each year making about 1/trillion atmospheric carbon atoms radioactive C.
Then an age can be obtained for the organic material.
Trees are a ubiquitous form of plant life on planet Earth.Tags: Adult Dating, affair dating, sex dating
