A beta particle. This is because the mass number is the same, so it cannot involve a neutron or a proton. Beta particles can either be a positron or an electron. A positron is just a positive electron. Because the atomic masses are the same, but the atomic number is different, you need an electron or positron, to negate the difference.
As carbon-14 decays, it transforms into nitrogen-14 through the process of beta decay. So, the amount of nitrogen-14 increases as carbon-14 decays.
An alpha particle is emitted when Pu-240 decays to U-236. It consists of two protons and two neutrons and is commonly emitted in alpha decay processes.
Polonium, which has an atomic number of 84, decays to astatine, which has an atomic number of 85, a negative beta particle is emitted.
An Alpha particle, and associated gamma radiation from the excited nucleus.
It is the reverse: Np-235 decay to U-235 by electron capture.

When P-32 decays to S-32, a beta particle is emitted. This beta particle is an electron released during the conversion of a neutron into a proton within the nucleus of the atom.
It is negative beta particle emitted by a uranium nucleus and converting it to neptunium nucleus.

When an atom of 85Kr spontaneously decays, it emits a beta particle. This decay process involves the transformation of a neutron into a proton, with the emission of an electron and an antineutrino.
It is the reverse: Np-235 decay to U-235 by electron capture.
An alpha particle is emitted when Pt-190 decays to Os-186. An alpha particle has a mass number of 4, and an atomic number of 2. When Pt-190 decays to Os-186, the mass number drops by 4, showing that an alpha particle is emitted, along with energy. The other form of particle that could be emitted is a beta particle, which has a mass number of 0. The difference between 190 and 186 is 4, thus showing the emission of an alpha particle.

Potassium-40 decays by emitting a beta particle, which is an electron. This decay process transforms potassium-40 into calcium-40.
When Na-20 decays to Ne-20, it emits a beta-minus particle, which is essentially an electron. This is because in beta-minus decay, a neutron is converted into a proton, releasing an electron and an antineutrino.
