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.
alpha
alpha ray.
Alpha particles.
No, alpha particles are not the most radioactive emission. Gamma rays are more penetrating and more energetic than alpha particles, making them the most dangerous and damaging form of radiation.
emission of alpha, beta or gamma particles
The radioactive decay of americium 241 is by alpha disintegration; the disintegration of radioactive krypton isotopes is by beta particles emission.
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).
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.
A = mass number = sum of p+ and n0 Z = atomic number = no. of p+ An alpha particle consists of two protons and two neutrons, so if an one were to be emitted from a radioactive atom, the atomic number (Z) would be reduced by two, and the mass number (A) would be reduced by four.
The other product of the radioactive decay of 204 Pb to 200 Hg is an alpha particle (4 He nucleus). This decay process involves the emission of an alpha particle, leading to the formation of 200 Hg.
This process describes radioactive decay, where an unstable radionuclide spontaneously transforms into a more stable form by emitting particles (alpha or beta) or photons (gamma rays). This emission reduces the nucleus' energy and brings it closer to a stable state.
When uranium radiates alpha particles, it transforms into thorium. Thorium is a radioactive element that is produced as a result of the decay of uranium through alpha emission.
