Which of the following is true of electron capture?
A) It decreases the nuclide's mass number by 2.
B) It is most likely to occur when the neutron:proton (n:p) ratio of the nuclide is too small.
C) It is most likely to occur when the nuclide is formed in an excited state.
D) It is most likely to occur when the neutron:proton (n:p) ratio of the nuclide is too large.
Homework Answers
answer : B) It is most likely to occur when the neutron:proton (n:p) ratio of the nuclide is too small.
explanation :
1) electron capture occurs generally when neutrons and protons are below the band line stability . that means band line below stability indicates lesser N/R ratio. above band line stability indicates more N/P ratio
so in electron capture proton converts into neutron will increase the N/P ration more and gets stability

Which of the following statements is True? (a) The valley of stability is the geographic location where many of the known nuclides were first discovered. (b), If N/Z ratio is too low , there are too many neutrons and the nuclide will undergo beta decay. (c) If N/Z ratio lies somewhere below 1 , the nuclide is stable. (d) If N/Z ratio is too high , there are too many protons and the nuclide will undergo position emission or electron...

Write the equation for electron capture. Hint: In electron capture, a particular type of weak force causes a nuclear transition: 1) An electron from the closest energy level interacts with the weak force, after the proton becomes a neutron due to a quark change for some reason; 2) A neutrino is emitted due to the electron interacting with the particular type of weak force; 3) Another electron falls into the empty energy level and so on causing a cascade of...
