If an electron is released from the nucleus (and not from an electron shell) then it would have been emitted by a neutron in beta decay. In beta-minus decay, a neutral neutron emits an electron and an anti-neutrino and becomes a proton; in beta-plus decay, a proton emits a positron and a neutrino and becomes a neutron.
There are two types of beta decay, and they are beta plus (beta +) decay and beta minus (beta -) decay. A post already exists on beta decay, and a link to that related question can be found below.

The sign of the charge depends if it's a beta-minus particle (an electron) or a beta-plus particle (a positron, or anti-electron). The former is negative, but the latter is positive. Generally, when we say "beta particle," we mean "beta-minus particle," but this is not always the case! For an element that decays via beta, check the locations on the periodic table (or better yet, the table of nuclides!) of the parent and daughter atoms. If the atomic number of a nucleus increased by one when undergoing beta decay (it now has an extra proton), it underwent beta-minus decay. If the atomic number decreased by one, it underwent beta-plus decay. Important note: we have just discussed the sign of the beta particle's charge, not the charge itself. The charge, in SI units, is 1.6022 x 10^-19 Coulombs. This quantity is, again, negative or positive depending on whether the particle in question is a beta-minus or beta-plus.
No, a delta particle is not a fast moving electron given off by a nucleus during radioactive decay. The electron described here is a beta particle, and specifically a beta minus particle. It is given off in (no surprise) beta minus decay. A link to a related question can be found below.
neutral charge. this is because a beta decay gains a proton and loses a neutron.
Beta particles, from beta- decay, have a charge of -1. Beta particles, from beta+ decay, have a charge of +1. Alpha particles have a charge of +2.

It is in beta minus decay that we see an electron appear to leave the nucleus of an atom. The electron is called a beta minus particle, or we might term that electron beta minus radiation.
If an electron is released from the nucleus (and not from an electron shell) then it would have been emitted by a neutron in beta decay. In beta-minus decay, a neutral neutron emits an electron and an anti-neutrino and becomes a proton; in beta-plus decay, a proton emits a positron and a neutrino and becomes a neutron.
The beta minus decay of polonium isotopes is extremely rare. Beta decay involve the increase of the atomic number with 1.Example: Po-218----------------beta minus---------------At-218

The difference between a beta plus and beta minus particle is the electrical charge. The charges are equal, but opposite. The beta minus particle is an electron with a negative charge, while the beta plus particle is an anti-electron or positron with a positive charge.
The natural isotope 227Ac decay: - by beta minus decay: to 227Th - by alpha decay: to 223Fr
Both Beta plus (positrons) and beta minus (electrons) are elementary particles the same as quarks.
Beta Particles have a negative charge,In Beta decay a neutron changes into a proton and a beta particle, an electron.
