Unlike chemical reaction rates, which vary with the conditions of a reaction, nuclear decay rates are constant. How do scientists determine the age of an object that contains carbon-14?

Nuclear decay is also called radioactive decay, and it occurs in a series of sequential reactions until a stable nucleus is reached. Nuclear reactions release much more energy鈥攐rders of magnitude more鈥攖han exothermic chemical reactions.

In radiocarbon dating, the age of an object is determined by comparing the object’s carbon-14 levels with carbon-14 levels in the atmosphere. A nuclear decay rate describes how fast nuclear changes take place in a radiaactive substance. Nuclear decay rates are constant even with diff temperature, pressure, surface area.

Nuclear Reaction. Chemical reaction normally occurs outside the nucleus. Nuclear reaction happens only inside the nucleus. When chemical reactions occur elements hold their identity and the nuclei of atoms also remains unchanged. During nuclear reactions, the nuclei of atoms changes completely and new elements are formed.
