PHY 104 Atomic Structures Objective Question

Question

What is the primary reason for nuclear instability in atoms with large atomic number Z?
Options
A Too few electrons in the electron shells.
B The large electrostatic repulsion between protons.
Correct Answer
C Insufficient number of neutrons to balance electrons.
D The atom being spherical in shape.
Correct Answer

Option B is the correct answer.

Detailed Explanation

The text states: 'Atoms with large atomic number Z often have more neutrons than protons to overcome the electrostatic repulsion between the protons to keep the nucleus stable. As Z gets larger and larger, a point is reached where increase in the number of neutrons is not sufficient to overcome the electrostatic repulsion between the protons this leads to nuclear instability.'

Hint

Think about the forces acting within a large nucleus, specifically involving charged particles.
