Currently the beta radioactivity of unstable atomic nuclei is often associated with the nuclear weak force that manifests within two kinds of nucleons and in their immediate environment. The W+ and Wconveyed bosons serve as temporary particles and are of short existence during intermediate phases in the transformative changes. The new concept and detailed explanation of beta radioactivity, here proposed, appealed mainly to the physical phenomenon of the electric combination between quarks of the nucleons that are a priori spatially involved in this reaction. We therefore propose that an unbound solitary nucleon (due to instability) and moving inside the nucleus, gets close enough to the other type of nucleon. While it is established that the effects of reciprocal electrical combination show that the feasibility and thereof consequences are perfectly consistent with the results seen for beta radioactivity. The involved ubiquitous electric physical processes illustrate, it seems, the merits of this new simply physicist approach regarding the reconsidered transformation modes of beta radioactivity that are here mainly of electrical origin and consequences.
