Why alpha emission occur first?

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.

Would an atom of radioactive gold be more likely to decay by alpha emission or beta emission?

Gold never decays by alpha emission, it either decays by -beta, +beta, K capture, or gamma emission depending on isotope.Natural gold is isotopically pure gold-197, which is stable.

Thorium-234 don't emit alpha particles.


Why doesn't alpha decay occur for sodium?

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.

What is the reason for alpha decay process?

The reason for all types of radioactive decay is the instability of the nucleus, some unstable nuclei become stable by alpha emission and some by beta emission.


What radioactive emission is a particle?

Alpha emission is a 4helium nucleus, which behaves like a particle. Beta emission is an electron, which behaves like a particle. Gamma emission is a photon, which behaves like a particle. Experiments can also be set up to show their wavelike properties (for alpha, beta, and gamma radiation).


What is the nuclear equation radionclide X decays by alpha emission into radium-224?

Alpha emission means that an alpha particle (2 protons + 2 neutrons) are emitted, so the original nucleus has 2 protons and 2 neutrons more.
