Because the less protons are in an atom the quicker it decays.
Radioisotopes have unstable nuclei. So alpha beta decay occurs mostly in them.
Alpha decay requires two protons and two neutrons. Hydrogen only has one proton.
Yes, but only if the nuclear disintegration is alpha decay. Alpha decay is only one mode of radioactive decay, and in alpha decay, a helium-4 nucleus (the alpha particle) will appear. Beta decay (two types) and spontaneous fission are also modes of radioactive decay, and different particles appear in those events.

1- 218 Po if emits one alpha and two beta particles it becomes 214 Po 2- 214 Po if emits one alpha and two beta particles it becomes 210 Po. This is all hypothetical.
Because the mantle rock is opaque, most radiation (except for radioactivity from decay of uranium and other radioisotopes) cannot pass through it. Radiation from radioisotopes (e.g. x-rays, gamma rays, beta rays) occurs in earth's mantle and can go significant distances before being absorbed by the rock, helping to keep the mantle hot.
The physical and chemical decay is not possible in vacuum but nuclear decay can neither be stopped.
Alpha decay requires two protons and two neutrons. Hydrogen only has one proton.
The question is unclear. First before what? More likely to occur? I am going to assume the latter... Alpha decay is more likely to occur, when both alpha and beta are possible, because alpha decay removes more binding energy from the nuclide, and the tendency is to reduce energy as quickly as possible.

The equation for the beta decay of 87Kr is: 3687Kr --> 3787Rb + -10e where -10e represents a negative beta particle or electron.
Gamma decay is the release of energy, but does not in itself change the nucleas Alpha decay is the loss of 2 protrons and 2 neutrons, lowering the atomic number by 2 and mass number by 4 Beta can occur as a result of a neutron turning into a protron, raising the atomic number by 1 and charge by 1
Any gas helps decay to occur.

Alpha decay is the emission of an alpha particle, which as two protons and two neutrons, and is, therefore, essentially a helium ion moving very fast. Alpha particles are trapped in potential wells in the atoms from which they are eventually emitted. The emission happens when the particle goes through a quantum process called tunneling. In order for the alpha particle to have been trapped, the nucleus has to be big enough to trap it. The smallest nuclei big enough to do this are isotopes 106 through 110 of tellurium.
