Classification of Nuclides

On the basis of the number of neutrons and protons constituting the nucleus, the nuclides (which refer to the atomic nucleus without relation to the outer sphere)
i) Isotopes
ii) Isobars
iii) Mirror nuclei
iv) Isotones
v) Nuclear isomers
Classification on the basis of nuclear stability
i) Stable nuclides
ii) Unstable or radioactive nuclides

The atomic mass of \[\ce{^32_16S}\] is 31.97 u. If masses of neutron and H atom are 1.0087 u and 1.0078 u respectively. What is the mass defect?

Name the most stable nuclide known.

Give an example of mirror nuclei.

Write pairs of isotones and one pair of mirror nuclei from the following:

\[\ce{^10_5B, ^12_6C, ^27_13Al, ^11_6C, ^28_14S}\]

Represent graphically log₁₀ (activity/dps) versus t/s. What is its slope?

Find the number of α and β-particles emitted in the process \[\ce{^222_86Rn -> ^214_84Po}\].
