Possible values are: 1 (K), 2 (L), 3 (M), etc.The state of each electron is determined by the four quantum numbers:.N electrons = 2 n 2, where N electrons designates the number of electrons in shell n.If the number of half-lifes n are known we can calculate the percentage of a pure radioactive sample left after undergoing decay since the fraction remaining = (1/2) n.Δ m /Δ t = rate of decay where Δ m = change in mass, Δ t = change in time.Gamma (γ) ray = no mass, no charge, just electromagnetic energy.A positron = +1e 0 (same mass as an electron but opposite charge).

Annotated Equation SheetĪs it is with the equation sheet, some constants are provided. this is NOT the equation sheet provided on the contest. The next link is an "annotated" equation sheet explaining what each of the equation represents. This table contains links to definitions of physical quantities, phenomena, and units, primarily in the International System of Units (SI) and the meter-kilogram-second (MKS) system. The following is a link to the most recent version of the equation sheet. The equation sheet has changed over time with many changes coming in both 20. it has many of the basic equations but it is not, nor is it intended to be, an exhaustive list of what may be used on the questions.
However, it does NOT include all possible formulas that might be useful on the contest. YES! The equation sheet is provided to students.
