In unstable nuclei the strong nuclear forces do not generate enough binding energy to hold the nucleus together permanently. The unstable nuclei lie above or below stablity line in proton and neutron stablity line. When there are more number of protons in nucleus then there is more repulsive forces between these protons and binding energy per nucleon decreases. Hence nucleus become unstable or radoactive. Beta decay, alpha decay, gamma decay, electron capture, nuclear fission and nuclear fusion are different interactions in nucleus through which nucleus try to obtain stability.
I will be glad to see your comment if you have any query and thumbs up if you are satisfied. Thanks...

If a substance is radioactive, this means that the nucleus is
unstable and will therefore decay by any number of processes (alpha
decay, beta decay, etc.). The decay of radioactive elements follows
first-order kinetics. Therefore, the rate of decay can be described
by the same integrated rate equations and half-life equations that
are used to describe the rate of first-order chemical
reactions:
lnAtA0=−kt
and
t1/2=0.693k
where A0 is the initial amount or activity, At
is the amount or activity at...

An unstable nucleus with a mass of 16.3 × 10−27 kg initially at
rest disintegrates into three particles. One of the particles, of
mass 4.9 × 10−27 kg, moves along the positive yaxis with a speed of
4.5 × 106 m/s. Another particle, of mass 8.7 × 10−27 kg, moves
along the positive x-axis with a speed of 3.4 × 106 m/s.
a) Find the speed of the third particle. Answer in units of
m/s.

moves in the positive y-direction with speed
v1 = 5.4 ✕ 106 m/s.
Another particle, of mass
m2 = 8.0 ✕ 10−27 kg,
moves in the positive x-direction with speed
v2 = 3.2 ✕ 106 m/s.
Find the magnitude and direction of the velocity of...

A neutron in a nuclear reactor makes an elastic,
head-on collision with the nucleus of a carbon atom initially at
rest.
(a) What fraction of the neutron's kinetic energy is transferred to
the carbon nucleus? (The mass of the carbon nucleus is about 12.0
times the mass of the neutron.)

(b) the initial kinetic energy of the neutron is 3.10
10-13 J. Find its final kinetic energy and the kinetic energy of
the carbon nucleus after the collision.
