Question

Under what condition does electron capture occur as an alternative to beta-plus decay?
Options
A When there is an excess of neutrons.
B When there is sufficient energy for beta-plus decay.
C When there is an excess of protons but insufficient energy for beta-plus decay.
Correct Answer
D When the nucleus is in an excited state.
Correct Answer

Option C is the correct answer.

Detailed Explanation

The text states: 'In the case of excess protons, where there's no sufficient energy for β+ decay to take place, an alternative process called electron capture can occur.'

Hint

Consider the conditions under which a proton might convert to a neutron, and when beta-plus decay might be energetically unfavorable.
