The atomic number and mass number play a big role in how stable a nucleus is. But, figuring out what that means can be a bit tricky.

1. Atomic Number (Z):

   • A higher atomic number means more protons in the nucleus.
   • When there are many protons, they push away from each other.
   • In big nuclei, this pushing can make them unstable.

2. Mass Number (A):

   • This number shows the total count of neutrons and protons.
   • If there are too few or too many neutrons compared to protons, the nucleus might break down.

Solution:

• To make nuclei more stable, scientists can create controlled environments.
• For example, they use machines called particle accelerators to help with this.
