Complete the following nuclear change:
\[\ce{^24_11 Na -> ...Mg.... + ^0_-1β}\]
An imaginary radioactive element `"_92X^235` decays to form X1; X2; X3; X4; X5 and X6 nuclides, by ejecting two β-particles, followed by α-particles and again two β-particles, followed by α-particle. Represent the various nuclear changes in the form of an equation. State the mass number and atomic number of X6. List the isotopes and isobars in the above nuclear equation.
The isotope of 92U235 decays by alpha emission to an isotope of Thorium (Th). The Thorium isotope decays by beta emission to an isotope of Protactaminum (Pa). Write down the equations to represent these two nuclear changes.
The nucleus of an atom does not contain electrons. Explain how is it possible for the nucleus to emit a beta particle which is fast moving electron.
