An element's radioactive decay can be determined through a single equation which requires imputing the isotope's half life, its rate of decay and the decay time since the rate of decay is measured.

Exponential growth and decay can be determined with the following equation: N = (NI)(e^kt). In this equation, "N" refers to the final population, "NI" is the starting population, "t" is the time over which the growth or decay took place and the "k" represents the growth or decay constant. If necessa

One formula for calculating yearly compound interest is M=P(1+i)n. "M" represents the final amount with the principal and interest combined, "P" represents the principal amount, "i" represents the interest rate, and "n" is the number of years invested.

A compound refers to any substance that contains two or more elements that have been joined together chemically. All compounds are molecules; however, not all molecules are compounds. Molecules such as O2 or H2 are not considered compounds because they only contain a single element.

Writing a beta decay equations involves denoting the emission of a beta particle as the loss of an electron. Beta decay involves a neutron decaying into a proton and an electron emission (beta particle); the atomic number increases by one, but the mass number remains the same. The lost electron does

The equation for gamma decay is Axy equals Axy plus the gamma symbol, where A is the parent particle's atomic symbol, x is the particle's total number of neutrons and protons, and y is the total number of protons. The gamma symbol indicates a emission of gamma energy.

Alpha decay happens when a radioactive particle decays into an alpha particle (helium-4 nucleus) and a new particle. The new particle has an atomic number that is two less than the original radioactive particle and an atomic mass equal to four less than the original particle.
