Radioisotopes – isotopes with unstable nuclei that go through changes. Spontaneously release the excess energy in the form of particles , energy and/or light to become stable

Unit 14: Nuclear CHemistry. Section 3: Radioactive Decay and Half-Life. Radioactive Decay. The spontaneous emission of rays or particles from certain nuclei as they “decay,” such as Uranium . These rays or particles are called nuclear radiation . They come in three types:

Nuclear Chemistry. Nuclear Medicine. Nuclear radiation can be used to visualize or test structures in your body to see if they are operating properly e.g. labeling atoms so their intake and output can be monitored

Nuclear Weapons. 5113. Number of operational warheads in the U.S. nuclear stockpile, according to the Pentagon. The figure is down from a peak of 31,225 weapons in 1967. Bulletin of the Atomic Scientists estimated in 2009 that Russia has 4,830 operational

DNA. Chapter 11. What is DNA?. DNA = Deoxyribonucleic Acid DNA is the complete instructions for making all the proteins for an organism. The Structure of DNA. DNA is a polymer made of repeating subunits called nucleotides . Nucleotides have three parts: 1. simple sugar ( deoxyribose )

General, Organic, and Biochemistry, 7e. Bettelheim, Brown, and March. Chapter 9. Nuclear Chemistry. Introduction. In this chapter, we study some of the properties of the nucleus, its particles, and nuclear radiation Nuclear radiation: radiation emitted from a nucleus during nuclear decay

Ch 9 Nuclear Decay. Review from ch 4… Atomic number (Z) tells you number of protons Always the same for an element; change the atomic number and you change the element Mass number (A) tells you number of protons + neutrons c an change as number of neutrons changes for each isotope.
