Nuclear Energy

2. Radiation - This is the most dangerous type of radioactive decay. Only high energy raises, therefore the element DOESN’T change.
3. Particle - a particle usually composed of protons, neutrons and electrons.
6. Particle - This is the least dangerous type of radioactive decay. It has 2 protons and 2 neutrons.
8. Particle - A neutron turns into a proton an an electron is emitted. It has 1 electron and energy.
9. - the central and most important part of an object, movement, or group, forming the basis for its activity and growth.
13. - This is when the mass of an atom is different from the mass of the same element.
14. - The atomic number of a certain element.

1. - the ability of an atom to emit (release) mass (subatomic particles) and energy. This process os called radiation.
4. Reaction -- a chemical reaction or other process in which the products themselves promote or spread the reaction, which under certain conditions may accelerate dramatically.
5. Number - The atomic mass of a certain element.
7. - the amount of time it takes for a substance to decay by half.
10. - a nuclear reaction in which a heavy nucleus splits spontaneously or on impact with another particle, with the release of energy.
11. - a subatomic particle of about the same mass as a proton but without an electric charge, present in all atomic nuclei except those of ordinary hydrogen.
12. - a reaction in which two or more atomic nuclei, combine to form one or more different atomic nuclei and subatomic particles
