Question

Determine the identity of the daughter nuclide from the beta decay of  Tc.

Quizplus · Accepted Answer

In beta decay, a neutron is converted to a proton and an electron. The proton remains in the nucleus, increasing the atomic number, and the electron is emitted as a beta particle. From the given parent nuclide, 11 Tc, a beta particle is emitted indicating that the daughter nuclide must have one more proton than Tc, therefore increasing the atomic number by 1. Among the choices, only option E, 11ea67b3_968f_6c3f_8b3b_c586c3cd3445_TB6103_11 Ru, has an atomic number that is one greater than technetium (Ru has atomic number 44 and Tc has atomic number 43), so it is the best choice for the daughter nuclide.
