Unit 4 Lesson 3 Nuclear Reactions What happens during a nuclear reaction? A nuclear reaction is a change that affects the nucleus of an atom. It differs from a chemical reaction in several ways. One difference is that chemical reactions do not change the mass of atoms, but nuclear reactions do so by a very small amount. Another difference is that nuclear reactions change the nucleus of an atom.
They can change the number of neutrons They can change the number of protons changing one type of atom into another. Isotopes of the same element have different numbers of neutrons and from that, different mass numbers.
Carbon atoms have 6 protons and 6 neutrons in their nucleus, giving them an atomic mass of 12 When carbon atoms lose or gain neutrons, they become isotopes. The mass number is added to the end of the name of an element to identify isotopes, such as carbon and carbon Unit 2 Lesson 3 Absolute Dating How can the absolute age of rock be determined? Radioactive isotopes, also called radioisotopes, are isotopes that are unstable and break down into other, stable isotopes by a process called radioactive decay.
As they break down, they release excess energy by emitting radiation in the form of alpha, beta and gamma rays. The radioactive isotope is called the parent isotope, and the stable isotope formed by its breakdown is called the daughter isotope. Half-life is the time needed for half of a sample of a radioactive element to undergo radioactive decay and form daughter isotopes.
Scientists study the amounts of parent and daughter isotopes to date samples. Finding the absolute age of a sample by determining the relative percentages of a radioactive parent isotope and a stable daughter isotope is called radiometric dating. Unit 2 Lesson 3 Absolute Dating What is the best rock for radiometric dating?
Igneous rocks are the best types of rock samples to use for radiometric dating.

Caravaggio Michelangelo Merisi or Amerighi was born in Milan, where his father, Fermo Fermo Merixio , was a household administrator and architect-decorator to the Marchese of Caravaggio, a town not far from the city of Bergamo. Like this lesson Share Imagine braving the desert heat for days or even weeks as you dig for dinosaur bones. You find something extraordinary and want to know as much about it as you can. In this lesson, you'll learn how scientists determine the absolute age of materials.
What is Absolute Age? Scientists who study the ancient Earth have been working for hundreds of years to build an accurate timeline of the formation of the planet and the evolution of all life. This is no simple task! In order to build and improve this timeline, scientists must have several types of accurate methods they can use to determine the ages of materials. There are two main categories by which they do this: In relative age dating, scientists study a material and compare it to other similar materials in order to establish a timeline.
