Question

The instability of a nucleus is due is due to :

• A. high proton electron ratio
• B. high electron neutron ratio
• C. low proton electron ratio
• D. low protons neutron ratio

Answer 1

Answer: (D)

low protons neutron ratio

The instability of a nucleus is due is due to low proton to neutron ratio or high proton to neutron ratio.
When neutron to proton ratio is less than 1, alpha emission occurs. When it is greater than 1.5, beta emission occurs.
