(a) Write the basic nuclear process involved in the emission of β+ in a symbolic form, by a radioactive nucleus.
(b) In the reactions given below:
(ii)`""_6^12C+_6^12C->_a^20 Ne + _b^c He`
Find the values of x, y, and z and a, b and c.
Derive the mathematical expression for law of radioactive decay for a sample of a radioactive nucleus
State the law of radioactive decay. Hence derive the expression N = Noe-λt where symbols have their usual meanings.
Write symbolically the process expressing the β+ decay of `""_11^22Na`. Also write the basic nuclear process underlying this decay.
The decay constant of radioactive substance is 4.33 x 10-4 per year. Calculate its half life period.
