An alpha particle is a positively charged nuclear particle consisting of two protons bound to two neutrons. The atomic number of an atom decreases by 2 and the mass number decreases by approximately 4 when an alpha particle is ejected.

What happens to the atomic number when an alpha particle is given off?
Alpha emission in an atom reduces its atomic number by two. A link can be found below to the related question about what alpha decay 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.
Nucleus of the chemical element atomic number 2 emitted by some radioactive substances?
alpha particle, He nucleus
When an unstable nucleus produces an alpha particle by how many units does the atomic number of the nucleus change?
An alpha particle is a helium nucleus, which consists of 2 protons and 2 neutrons. When an unstable nucleus emits an alpha particle, it loses 2 protons, which means its atomic number will be reduced by 2.
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).
What happens to the atomic number when an alpha particle is given off?
Alpha emission in an atom reduces its atomic number by two. A link can be found below to the related question about what alpha decay is.
What is the change in the atomic number when the 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 happens to the atomic number of an element if it emits 1 alpha particle and 1 beta particles?
It drops 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.
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.
When radium atomic number 88 emits an alpha particle the resulting nucleus has atomic numbers?
226Ra------------alpha particle----------222Rn (radon, a radioactive gas)
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 happens to the atomic number of an element if it emits 1 alpha particle and 3 beta particles?
It depends on whether the beta decay is beta- or beta+. The alpha emission reduces the atomic number by 2. Beta- increases the atomic number by 1 while beta+ decreases the atomic number by 1. You do the math.
When radium emits an alpha particle the resulting nucleus has atomic number?
The result is radon, atomic number 86. 226Ra - alpha particle = 222Rn (radon, a radioactive gas)
When uranium-238 atomic number 92 decays by emitting an alpha particle it becomes?
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 particle will be emitted probably by an isotope with an atomic number greater than 83?
An Alpha particle
Nucleus of the chemical element atomic number 2 emitted by some radioactive substances?
alpha particle, He nucleus
