Question

Which equation correctly represents electron capture by the  nucleus?

Quizplus · Accepted Answer

The equation for electron capture by the 11eb6c5c_3a2a_8cc9_8d9d_1d8310d3923a_TB8482_11 nucleus is written as: 11eb6c5c_3a2a_b3dc_8d9d_a3d1f7b89828_TB8482_11. This is because in electron capture, a proton in the nucleus captures an electron from the inner shell, converting the proton into a neutron and emitting a neutrino. This reduces the atomic number of the element by one but does not change the mass number, so the resulting nucleus is written as: 11eb6c5c_3a2a_b3dc_8d9d_a3d1f7b89828_TB8482_11. Choice C is the only one that has the correct change in the prefix before the third and fourth groups of digits, indicating the conversion of a proton to a neutron.
