Q. The unstable nature of a nucleus signifies that:
Which of the above statements is/are correct?
Q. The unstable nature of a nucleus signifies that:
Which of the above statements is/are correct?
The correct option is B 2 and 3 only
Explanation:
Statement 1 is incorrect: An atom is stable if the forces among the particles that make up the nucleus are balanced.
Statement 2 is correct: Too many protons in the nucleus result in an imbalance between forces, which leads to nuclear instability. If the attractive interactions due to the strong nuclear force are weaker than the electrostatic repulsions between protons, the nucleus is unstable, and it will eventually decay.
Statement 3 is correct: If a nucleus has too many neutrons, the neutrons will turn into a proton and emit fast-moving electrons. This electron is called a beta (β) particle - this process is known as beta radiation.
