Question

Determine the identity of the daughter nuclide from the electron capture by  Be.

Quizplus · Accepted Answer

Electron capture occurs when a proton-rich nuclide with low atomic mass captures an inner-shell electron and converts a proton into a neutron, emitting a neutrino and a gamma ray. In this case, the electron capture by 11eacb30_68c5_4981_b5a4_c7ccce17e152_TB7901_11_TB7901_11 Be results in the conversion of a proton into a neutron, changing the atomic number from 4 to 3. Therefore, the daughter nuclide should have an atomic number of 3, which corresponds to lithium (Li). The correct option containing Li is option D.
