(a) Explanation Consider that all the S 87 r is came from R 87 b . Write the expression for number of particles left after a time in radioactive decay. N = N 0 e − λ t Here, N is the number of particles left after a time in radioactive decay, N 0 is the initial number of particles, λ is the decay constant, t is the time. Re-arrange the expression to find the time t . t = − 1 λ ln ( N N 0 ) (I) Write the expression to find the half-life. T 1 / 2 = ln 2 λ (II) Here, T 1 / 2 is the half-life. Substitute equation (II) in (I) to find the time t (b) To determine Whether the rock is actually much older and the assumption used in the radioactive dating method.

Radioactive decay

The emission of energy to produce ionizing radiation is known as radioactive decay. Alpha, beta particles, and gamma rays are examples of ionizing radiation that could be released. Radioactive decay happens in radionuclides, which are imbalanced atoms. T…

Artificial Radioactivity

The radioactivity can be simply referred to as particle emission from nuclei due to the nuclear instability. There are different types of radiation such as alpha, beta and gamma radiation. Along with these there are different types of decay as well.
