Chapter 19 & 20

5. Nuclear process in which extra neutrons induce some very heavy nuclei to split apart into smaller and more stable nuclei.
6. Type of chemistry branch that Concerned with changes in an atom’s nucleus (protons & neutrons) that affect the atom’s electrons and release radiation.
9. The branch of science that combines the disciplines of chemistry, engineering, and materials science to manipulate atomic or molecular substances for the purpose of creating useful products to benefit mankind.
11. Type of decay that has a positive charge and

1. What keeps a nuclei together.
2. nuclear process in which extra neutrons are then brought together to create a more stable nuclei.
