Study questions carbon dating
After death, this carbon 14 starts to leave the body in question.Hense, if a sycamore tree is created with 40,000 carbon 14 atoms and loose 48 a year, after a... Carbon dating tells how long ago something died (more specifically, when it stopped absorbing carbon).
There is a change in mass, since an electron and an electron anti-neutrino is emitted, and also because the neutron changes into a proton, but the atomic mass number , per se, does..main types are alpha decay in which an alpha particle (made of 2 protons and 2 neutrons) is emitted, beta decay (the emission of a beta particle such as an electron), and gamma decay in which a high-energy gamma photon is emitted Everything has what is called a half-life, it is the time in which a substance, such as carbon halves in quantity.
Some less less...nuclear decay is when the nucleus of an atom is broken apart.
because the number of protons has changed, so has the element.
This isotope has a half lifeof around 5...( Warning: This is a little long.
For a summary, scroll down to the bottom.) Depends on the kind of decay.
