If molybdenum-91 undergoes beta plus decay, or positron emission, the equation will look like this: 4291Mo => 4191Nb + e+ + ve In this reaction, a proton in the nucleus of the Mo-91 atom undergoes a change mediated by the weak interaction or weak force. This involves an up quark changing into a down quark, and the proton becomes a neutron. Nuclear transmutation takes place, and the Mo-91 atom becomes an atom of niobium, Nb-91. The positron, represented by e+, and a neutrino, the ve, will be ejected from the nucleus. Links can be found below if you wish to check facts and do some additional investigating.
