Activities

Mission NC1 Isotopes and Radioisotopes

Mission NC1 pertains to isotopes and the use of isotope symbols to represent the number of protons and neutrons in the nucleus of an isotope. The mission consists of 32 questions organized into 8 Question Groups.

Mission NC2 Nuclear Decay Processes

Mission NC2 requires that students understand the concept of nuclear decay and be able to recognize the four main decay processes (alpha, beta, gamma, and positron) based on their nuclear equation and affect upon the nucleus. The mission consists of 36 questions organized into 9 Question Groups.

Mission NC3 Nuclear Decay Particles

Mission NC3 pertains to the properties and symbols associated with the radiation emitted by nuclear decay; this refers to the alpha particle, beta particle, positron particle, and gamma ray. The mission consists of 36 questions organized into 9 Question Groups.

Mission NC4 Balancing Nuclear Equations 1

Mission NC4 pertains to the balancing of nuclear equations. Students must be able to sum atomic numbers and mass numbers of reactants (or products) in order to determine the missing isotope in a nuclear equation. The mission consists of 36 questions organized into 9 Question Groups.

Mission NC5 Nuclear Stability

Mission NC5 pertains to patterns associated with the stability of nuclei and the manner in which various decay processes lead to stability. Students should be prepared to reason scientifically from given information towards appropriate conclusions. The mission consists of 28 questions organized into 7 Question Groups.

Mission NC6 Strong Nuclear Force

Mission NC6 pertains to the forces of repulsion and attraction inside the nucleus. Students must be familiar with the electrostatic force and the strong nuclear force. The mission consists of 36 questions organized into 9 Question Groups.

Mission NC7 Half-Life

Mission NC7 pertains to half-life. Students demonstrate an understanding of half-life by analyzing and completing tables for the amount as a function of time. The mission consists of 28 questions organized into 7 Question Groups.

Mission NC8 Bombardment Reactions

Mission NC8 pertains to bombardment as a means of inducing nuclear transmutation. The mission consists of 24 questions organized into 6 Question Groups.

Mission NC9 Balancing Nuclear Equations 2

Mission NC9 pertains to the balancing of nuclear equations. Students must be able to sum atomic numbers and mass numbers of reactants (or products) in order to determine the missing isotope in a nuclear equation. The mission consists of 36 questions organized into 9 Question Groups.

Mission NC10 Binding Energy

Mission NC10 requires that students be able to compare the energy and the mass of a nucleus to the energy and mass of the nucleons of which it is composed. Students should be familiar with the meaning of mass defect, binding energy, and mass-energy equivalence.

Mission NC11 Nuclear Fission and Fusion

Mission NC11 pertains to nuclear fission and nuclear fusion. Students must be able to describe the two processes using words, diagrams, and nuclear equations. The mission consists of 32 questions organized into 8 Question Groups.
