What is missing in the following nuclear equation? 99/42 Tc > ? + 99/44 Ru A.neutron B.beta particle C.proton D.alpha particle

Answer:
You have mistyped the atomic number of Tc which is 43 not 42. The answer to your question is a beta particle e- You see a beta particle is emitted when a neutron decays into a proton, keeping the atomic mass the same but the atomic number increases by 1.

The equation should be 99/43 Tc -> 99/44 Ru + electron (beta minus particle) + electron antineutrino. Remember that Technetium is 43, not 42. 42 is Molybdenium.
