Question

• The heavy nucleus with low binding energy per nucleon are unstable. They attain stability by emitting​

Answer 1

Answer:

by attracting of electrons

as they are negative charged

Explanation:

Answer 2

The Decay of free neutrons is energy feasible because, the mass of neutron is greater than the sum of the masses of the proton & electron if decays into. But where a neutron is paired with a proton its decay is not energy feasible and thus such neutrons within nuclei are stable.
