No. Beta decay occurs when the Weak Force transforms a neutron to a proton or vice versa.
In beta radiation, an emission of electrons can occur due to beta decay. A neutron can disintegrate into protons and electrons.
A neutron changes to a proton.
Alpha decay decreases the atomic number by two. Beta- decay increases the atomic number by one. Beta+ decay decreases the atomic number by one. Gamma decay does not change the atomic number. However, gamma decay is often incidental to a precipitating alpha or beta event that upsets the energy equilibrium in the nucleus, so the two are not unrelated.
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.
Because the less protons are in an atom the quicker it decays.
Radium-226 does not decay by beta decay. It decays by alpha decay to radon-222.

Thorium 234: Beta decay. Atomic number increases by 1.
Beta decay is a property of atoms not molecules.
The end point energy of a beta decay is the kinetic energy of all particles emitted through B-decay. This is often ignoring the energy of the recoiling daughter nucleus.
