Basics $100 Answer Back to Jeopardy What is the atomic mass unit? 1 amu = 1 u = 1.66* kg

Basics $200 Answer Back to Jeopardy What are the parts of an atom? Proton positive charge in the nucleus of an atom. Atomic # (Z) = # of protons determine element Neutron neutral particle in the nucleus of an atom. Neutron # (N) = # of neutrons determine isotope Electron negative charge in the outer shell of an atom.

Basics $300 Answer Back to Jeopardy What is a Mass Number? A = Z + N

Basics $400 Answer Back to Jeopardy What is an isotope? Isotopes of a given element have the same number of protons in the nucleus but different number of neutrons. A 14 Element Name example C Z 6

Particles $200 Answer Back to Jeopardy When sulfur-35 (Z = 16) decays to chlorine-35 (Z = 17), a beta particle (electron) is emitted.

Particles $300 Answer Back to Jeopardy Nuclear radiation can be detected by using a Geiger counter.

Particles $400 Answer Back to Jeopardy Two particles that will be deflected by a magnetic field are alpha and beta particles.

Half-Life $100 Answer Back to Jeopardy When a nucleus in an excited state decays to the ground state, a gamma ray is emitted.

Half-Life $200 Answer Back to Jeopardy The time interval during which a nucleus has a 50% probability of decaying is its half-life.
