An alpha particle consists of 4 nucleons, which are 2 protons and 2 neutrons.
In alpha decay, an alpha particle is emitted from the nucleus of an atom, so the atom loses 2 protons, and a total of 4 nucleons.
The atomic number of an atom undergoing alpha decay is reduced by 2, the number of protons lost, and the mass number is reduced by 4, the number of nucleons lost.
The alpha decay of actinium-225 can be represented by the equation:
[^{225}{\ 89}\text{Ac} \rightarrow \ ^{221}{\ 87}\text{Fr} + \ ^{4}_{\ 2}\text{He}]
In this decay process, actinium-225 decays into francium-221 by emitting an alpha particle (helium-4 nucleus).
Alpha decay is represented as
ZXA(parent) ------>Z-2YA-4(daughter) + 2He4 (alpha particle) + Q
Where Z = atomic number, A = Mass number and Q represents energy released as a result of mass defect in the decay.
Beta- involves the transformation of a neutron into a proton, so the atomic number will go up by one, while the Atomic Mass number stays the same.
6C14 -> beta-, t1/2 = 5730 years -> 7N14 + e- + v-e
Beta+ involves the transformation of a proton into a neutron, so the atomic number will go down by one, while the atomic mass number stays the same.
6C11 -> beta+, t1/2 = 20.3 minutes -> 5B11 + e+ + ve

What is the nuclear decay equation for potassium-40?
There are three beta decay modes for 40K, and so three equations. The equation for the negative beta decay of 40K: 1940K --> 2040Ca + -10e where the -10e represents a beta particle or electron. The equation for the positive beta decay of 40K: 1940K --> 1840Ar+ 10e where the 10e represents a positive beta particle or positron. The equation for the decay of 40K by electron capture is:1940K + -10e --> 1840Ar + ve
What is a subatomic particle with two neutrons that is emitted during some types of radioactive decay called?
A subatomic particle with two neutrons that is emitted during some types of radioactive decay is called an alpha particle. It consists of two protons and two neutrons, and is used to reduce the mass and atomic number of the parent nucleus.
Protactinium-231 decays by emitting an beta particle and a gamma ray. What daughter nuclide is formed in this process?
Protactinium-231 decays by beta emission to form uranium-231 as the daughter nuclide. The gamma ray emission is a result of the daughter nucleus readjusting its internal energy state after the beta decay.
What is the nuclear equation for the decay of radium 226?
The equation for the alpha decay of 226Ra: 88226Ra --> 86222Rn + 24He The alpha particle is represented as a helium (He) nucleus.

Write a nuclear equation for the indicated decay of Uranium 234?
The equation for the alpha decay of 234U is: 92234U --> 90230Th + 24He representing the alpha particle as a helium nucleus. 234U also decays by spontaneous fission, but the results are somewhat unpredictable, so there is no standard equation.
How do you do nuclear decay equations?
To write nuclear decay equations, you would typically start with the parent nucleus and identify the type of decay (alpha, beta, gamma). Then, you would balance the equation by conserving mass number and atomic number on both sides of the equation. Finally, you write the decay products. Remember to include the correct particles emitted during the decay process.
How do you write a balanced nuclear equation for the formation of polonium-206 through alpha decay?
To write a balanced nuclear equation for the formation of polonium-206 through alpha decay, start with the parent nucleus, which is radium-210. Radium-210 undergoes alpha decay, emitting an alpha particle (helium nucleus) to form polonium-206 and an additional particle (usually a neutrino). The balanced nuclear equation for this process would be: (^{210}{88}Ra \rightarrow ^{206}{84}Po + ^4_{2}He).
What is The Balanced Nuclear Equations For The Alpha Decay Of Radium-226?
When radium-226 undergoes alpha decay, it becomes radon-222. We write the equation like this: 88226Ra => 24He + 86222Rn Here we see the alpha particle written as a helium-4 nucleus, which is, in point of fact, what it is. Notice that the numbers that are subscripted are equal on both sides of the equation, and the superscripted numbers are as well. They must balance for your equation to be correct.

What is a balanced equation for the alpha decay of thorium -232?
Alright so you begin with what you need, this isotope of Protactinium has 234 nucleons, its atomic number is 91, in Beta decay we release an electron, which has no nucleons (protons and neutrons) and an atomic number of -1 so when we take out -1 from 91, so 91 - -1 we get 92, which is of course Uranium, this particular isotope has 234 nucleons, now, to show where it has gone, write the electron in, and add a antineutrino aswell, heres how mine looks. Pa23491 ---> U23491 + e0-1 + antineutrino (a v with a little line above it) Hope this helps :)
