When a radioactive nucleus disintegrates by emitting a _____________ atomic number increases by one and mass number remains the same.

The same radioactive nucleus may emit

In a radioactive series a nucleus X distintegrates into nucleus Y by emitting two alpha and two beta particles. IF m and n are the mass number and atomic number of the nucleus X, then the mass number and atomic number of the nucleus Y respectively are

In the radioactive disintegration of "_A^ZX n alpha-particles are emitted . Find atomic number and mass number of the new nucleus formed by this disintegration?

A nuclide A (with mass number m and atomic number n ) disintegrates emitting an alpha and one beta particle. The resulting nuclide B has mass number and atomic number respectively equal to

A sample of a radioactive nucleus A disintegrates to another radioactive nucleus B, which in turn disintegrates to some other stable nucleus C. Plot of a graph showing the variation of number of atoms of nucleus B vesus time is : (Assume that at t = 0, there are no B atoms in the sample)

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

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

A radioactive atom having atomic mass 236 and atomic number "90" disintegrates by emitting p a- particles and q beta -particles only.If the atomic mass of final atom is 212 and atomic number is 80, then the value of p times q is

A certain radioactive nucleus emits a particle that leaves its mass number unchanged, but increases its atomic number by one. Identify the particle and write its symbol.
