Suggest which particles will be emitted as K-40 decays to Ca-39:
As the proton number increases by 1 from 19(K) to 20(Ca), the process of decay must be beta minus in order to conserve charge. This means that an electron (or beta plus particle) will be emitted along with an anti-electron neutrino in order to conserve the lepton number.
