Carbon dating nuclear chemistry updating a valentine 1
The process and the background science are described.
Radiochemistry and nuclear medicine certain chemical reactions and lab tests make use of the fact that two different isotopes of the same element have the same chemical properties even though they have different nuclear properties. How did an electron get into the nucleus in the first place?A child mummy is found high in the Andes and the archaeologist says the child lived more than 2,000 years ago.How do scientists know how old an object or human remains are?What methods do they use and how do these methods work?In this article, we will examine the methods by which scientists use radioactivity to determine the age of objects, most notably carbon-14 dating.
Unstable means that the atom is in a high state of potential energy and must change the composition of its nucleus in order to become more stable. Similarly, you can find the natural log of a number (log base e, where e is approximately equal to 2.71828 . As long as the amount of time that the substance decays is some whole number multiple of the half-life, then you can figure out the amount of the substance that remains using pencil and paper.
