What type of nuclear decay results in the atomic number decreasing by two and the mass decreasing by two?

Emission of an alpha particle.


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.


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 type of radiation does Radon give off?

Naturally occuring Radon gas decays by alpha particle emission. However, many of the decay chain products have very short half lives, of which some decay by alpha particle emission and others by beta particle emission.


Which is the heaviest and slow moving particle in nuclear instrumentation?

The heaviestis the alpha particle.


What type of radiation alpha beta or gamma is emitted by thorium-230?

alpha particles.


What is alpha particle detector and what is the application of bjt in alpha particle detector?

A Geiger counter, also called a Geiger-Müller counter, is a type of particle detector that measures ionizing radiation. They detect the emission of nuclear radiation: alpha particles, beta particles or gamma rays. A Geiger counter detects radiation by ionization produced in a low-pressure gas in a Geiger-Müller tube


When the nuclei of heavy atoms with many protons are split this process is called?

Generally this is called nuclear fission. In the special case where one of the new particles produced is a Helium-4 nucleus (2 protons, 2 neutrons) the process is radioactive decay and specifically alpha emission. (The He-4 nucleus is called an alpha particle, as it was the first such particle recognized. A beta particle is an electron emitted from the nucleus with the conversion of a neutron to a proton = beta emission.)


What represents an alpha particle?

An alpha particle in nuclear chemistry is a helium-4 nucleus, or 42He+2. In order to simplify, the Greek letter alpha is also used to represent the particle.


Which type of nuclear radiation (nuclear emission) has the greatest mass?

Alpha or an He nucleus because it has a mass of 4 when all the others have a mass of close to zero.
