In 1894 the physicist Stoney proposed the name electron(on being a Greek suffix); the names of the other elementary particles were formed by imitation.
Emitting a positron, turns a proton into a neutron. So the atomic number goes down by 1, while the mass number remains the same.
The three subatomic particles of an atom that are commonly referred to are the proton, the neutron, and the electron. The proton has a charge of +1 and is found in the atomic nucleus. The neutron has no charge and is also found in the atomic nucleus. Electrons have a charge of -1 and are found outside of the atomic nucleus in a place called the electron cloud.
SOME sub-atomic particles will decay into other particles. For example, a neutron will spontaneously change into a proton, an electron, and a neutrino.
Electrons have the least mass, with protons and then finally neutrons.
There are no positrons in the nucleus of any atom. Positrons are anti-electrons; they are antimatter. They could be said to be the antimatter equivalent of the electron, and, as such, they would be present around the nucleus of an antimatter atom as the electrons are present around the nucleus of a "regular" atom. Positrons can be produced in atomic nuclei by some kinds of radioactive decay, and they can be observed to be leaving a nuclear reaction called beta plus decay. But the positron leaves the nucleus of an atom as soon as it is created. It does not (cannot) exist in the nucleus of an atom.
Atoms have equal numbers of protons and electrons.
The beta particle will alter the electromagnetic field of the atom. An electron will add to the electromagnetic charge if emitted, and subtract from, if it is absorbed. A positron will do the opposite. The atomic nucleus will also change. an electron can convert a neutron to a proton if emitted, and a proton to a neutron if absorbed. The positron, again, will do the opposite.
Proton, neutron and electron At a lower level up quark, down quark, and electron
sub-atomic particles are within the atom (and remember, atoms are everywhere): the electron, proton and neutron are all sub-atomic particles, but there are even smaller particles (and anti-particles) called quarks that make up the proton, neutron and electron.
They are sub atomic particles. Neutrons does not contain charge.
The electron is the smallest of the three main atomic particles by a long way. The proton and neutron are of a similar size, with the neutron having (very) slightly more mass. The mass of an electron is around 1/1840 of a proton or electron.
There are 3 kinds of Sub-Atomic particles. These are Proton, Electron, Neutron.

Neutron: neutral Proton: positive Electron: negative
I'm guessing that it's the proton, the neutron and the electron.
The atomic particles of an isotope are the proton, electron and neutron
After positron emission or electron capture the atomic number is decreased with one.
