15.)  Artificial Nuclear Reactions • All human performed; not in nature – Alpha particle bombardment– Neutron Bombardment 16.) Artificial Nuclear Reactions • Alpha Particle Bombardment – He attacks target atom • Neutron Bombardment – n attacks target atom 17.) Transuranium Elements • Elements with atomic numbers higher than 92 (past uranium) – Very unstable – they decay within microseconds –Only found in laboratories now –Were probably found in the very beginning of the universe, but they all decayed a long, long time ago

Unformatted text preview: 18.) Half-Life Time required for of an isotope to decay Curve exponential 19.) Half life of iron-59 is 44.5 days. How much of a 2.0 mg sample remains after 133.5 days? 20.) 10.0 g sample of Sr-90 undergoes decay and0.625 g remains. How many half-livesoccurred? 21.) Binding Energy Energy that is stored in the nucleus Some of the mass of the particles that make up the nucleus is converted into the binding energy This energy keeps the repulsive protons packed together...
