Across
- 3. an ionic compound that contain metal ion or NH4+ and a nonmetal or polyatomic ion other than OH-
- 5. a process in which large nuclei are split into smaller pieces releasing large amounts of energy
- 6. the addition of base to an acid sample to determine the concentration of the acid
- 9. high-energy radiation emited to make a nucleus more stable
- 10. a nuclear particle identical to a helium ( He, a) nucleus (two protons and two neutrons)
- 12. a substance that dissolves in water and produces hydroxide ions (OH-) according to the Arrhenius theory; all of them are proton acceptors according to the Bronsted-Lawry theory
- 13. a radioactive atom of an element
- 14. ___________ decay is the process by which an unstable nucleus breaks down with the release of high-energy radiation
- 15. energy or particles released by radioactive atom
- 17. _________ acids and bases slightly dissociate in water
Down
- 1. a particle of radiation with no mass and a positive charge produced by an unstable nucleus when a proton is transformed into a neutron and a positron
- 2. the separation of an acid or a base into ions in water
- 3. __________ acid is an acid that completely ionizes in water
- 4. a fission reaction that will continue once it has been initiated by a high energy neutron bombarding a heavy nucleus such as uranium -235
- 7. the term that describes a solution with equal concentration of hydronium ions and hydroxide ions
- 8. a reaction between an acid and a base to form a salt an water
- 11. a reaction in which large amounts of energy are released when small nuclei combine to form larger nuclei
- 12. a particle identical to an electron that forms in the nucleus when a neutron changes to a proton and an electron
- 16. a substance that dissolves in water and produces hydrogen ions (H+), according to the Arrhenius theory; all of them are proton donors, according to Bronsted-Lawry theory
