The alpha particle is the nucleus of 4He, comprising two neutrons and two protons. It has a Atomic Mass of 4 and a charge of +2. As a result, it is the least penetrating of all the various emissions (alpha, beta, gamma, neutron) but, unfortunately, it can be the most devastating if it is absorbed, for instance, into the lungs.

What is the change in atomic number when an atom emits an alpha particle?

The atomic number will decrease by 2, the number of protons in the emitted alpha particle. An alpha particle is a helium-4 nuclei with two protons and two neutrons.


What is the composition of an alpha particle?

An alpha particle is a helium nucleus, two protons and two neutrons, but no electrons. The symbol is 24He2+.


When radium atomic number 88 emits an alpha particle the resulting nucleus has atomic numbers?

226Ra------------alpha particle----------222Rn (radon, a radioactive gas)


The radioactive alpha particle has the same structure as atomic nucleus of which gas?

The radioactive alpha particle has the same structure as the atomic nucleus of helium. They are usually formed and emitted during alpha decay.


What is the change in the atomic mass number when an atom emits an alpha particle?

Alpha particle consist of two protons and two neutrons so after alpha emission atomic number decreases by 2 and atomic mass by 4 units.


When radium atomic number 88 emits an alpha particle the resulting nucleus has what atomic number?

226Ra------------alpha particle----------222Rn (radon, a radioactive gas) The atomic number of radon is 86.


What is the atomic number of an alpha particle?

An alpha particle is actually the nucleus of a helium-4 atom. It's atomic number is two, just like the helium atom's is.


Is radium identical to an alpha particle?

No. Radium is a heavy metal, atomic number 88 (with 88 protons). An alpha particle is a helium nucleus, atomic number 2. Radium decays by each atom emitting an alpha particle, becoming Radon gas, atomic nubmer 86.


How does the atomic number change when alpha decay takes place?

An alpha particle is a helium nucleus, that is two protons and two neutrons. This means that when an alpha particle is emitted the atomic number decreases by two.

Helium


What happens to atomic number and atomic mass of an atom that emits alpha particle?

An alpha particle is a helium nucleus composed of 2 neutrons and 2 protons. Hence the atomic number will decrease by 2 and the atomic mass will decrease by 4.


What is the fusion product of the reaction of an alpha particle with Ne-20?

Look up the atomic number of Neon, add 2 to that (since an alpha particle has two protons), and add 4 to the atomic mass (since the alpha particle has 4 mass units).


If a radioactive nucleus with an atomic number of 88 emits an alpha particle what will the atomic number of the new nucleus be?

Two less, since the alpha particle takes away two protons.


What is the change in atomic mass number when an atom emits an alpha particle?

The atomic number will decrease by 2. An alpha particle is a helium-4 nucleus, and it contains a pair of protons and a pair of neutrons. During alpha decay, an atomic nucleus has its atomic mass decrease by 4, and its atomic number decrease by 2.


What happend to the atomic number of an element which emits alpha particle and two beta particle?

THe atomic number would decrease by 2 as alpha particle comes out. But for two beta particles the atomic number would increase by 2. So the atomic number remains unchanged due to emission of one alpha followed by 2 beta particles.
