Introduction: What is Nuclear Energy? (03:58)


The big bang took place 15,000 million years ago. Clouds, oceans, human being, mountains, and rocks are made up of matter, formed from just over 100 elements. Atoms contain a proton, neutron, and electron.

Nuclear Energy (02:06)

Elements are different in size and structure of atoms. Hydrogen has one proton and one electron. In nuclear fission, energy is obtained by dividing a nucleus into two smaller portions.

Nuclear Fission (02:58)

In this process, a heavy atom is bombarded with neutrons causing the nucleus to divide. A nuclear explosion occurs when a chain reaction is uncontrolled. A nuclear reactor uses cadmium to regulate the process.

Nuclear Fusion and Summary (03:49)

Fusion combines two smaller nuclei to form a heavier nucleus. Hydrogen must be heated to extremely high temperatures. Matter is made up of elements which contain atoms.

Everything in the universe is made out of matter, including living things. Learn about matter, the structure and composition of atoms, atomic numbers of different elements, and how these relate to nuclear energy. This program also covers the first nuclear fission ever by Otto Hahn, Albert Einstein and the relation between mass and energy, nuclear reactors, radioactive materials, and the Big Bang theory.
