What kind of change takes place in a nucleus when a `gamma`-particle is emitted ? Express it by an equation. State whether (a) atomic number, and (b) mass number are conserved in a radioactive `gamma`-decay ?

The atomic number and the mass number of an atom remains unchanged when it emits

Match the column in radioactive decay process of nucleus with atomic number Z and mass number A.

A uranium nucleus ._(92)U^(238) emits and alpha -particle and a beta -particle in succession. The atomic number and mass number of the final nucleus will be

A nucleus Pu emits an alpha particle and changes to U which emits a beta particle and then a gamma particle to change into ""_(93)^(235)Np . Write the above nuclear changes in form of an equation stating the atomic number and mass number of each nucleus.

State the relation between atomic number and atomic mass for light elements. State which elements are considered radioactive giving reasons.
