It's called alpha-decay. The two protons and two neutrons are removed in the form of alpha particles, or helium nuclei.

Thunder is created by?
Lightning is formed by particles in the clouds, that on the top forms a Positive charge, and on the bottom a Negative charge, these particles continue to form, and when there are to many particles in the clouds, some need to go, and when they go, they come out as Static electricity, which this is called Lightning, and the more particles there are, the more will need to be given, and that means the more lightning there is.
Is oxygen stable or radioactive?
Oxygen, under normal conditions, is non-radioactive. But there are traces of radioactive isotopes present which makes the oxygen slightly radioactive. Additionally, these isotopes have long half-lives, so the radiation given off will not be a lot within a period of time.
What is the half life of francium?
It is a period of time when the radio active mass is halved. Radioactive metals disintegrate. In this disintegration the radio active atom emits either/or alpha/beta/gamma particles, and in doing so the given elements changed to a less massive element. Taking uranium for example. The isotope 234-U decays with beta emission to the isotopic element 234-Protactinium.in a period of 24 days. So if you had say 10g of 234-U in 24 days you would have 5g of 234-U . The other 5g would be the element 234-Protactinoum.
What is the name given to the process of separating soil into its various soil particles and humus?
Sedementation
Which state of matter have the least particles in a given volume?
liquids because most things is either in a form of gas or solids
What is a high energy electron given off during radioactive decay called?
Beta Particles
What is half life of a isotope?
The half life of an isotope refers to the rate at which a radioactive isotope undergoes radioactive decay. Specifically, it is the amount of time it takes for half of a given sample of a radioactive isotope to decay.
How to identify the types of radiation given off by radioactive particles?
identify the given
When an atom undergoes radioactive decay when does it become a completely different element?
An atom of a given isotope will undergo radioactive decay whenever it feels like it. No joke. The nucleus of a radioactive isotope is unstable. Always. But that atom has no predictable moment of instability leading immediately to the decay event. We use something called a half life to estimate how long it will take for half a given quantity of an isotope to undergo radioactive decay until half the original amount is left, but this is a statistically calculated period. No one knows how long it will take a given atom of a radioactive isotope to decay, except that those with very short half lives will pretty much disappear relatively quickly.
Why is Radioactive decay is said to be random?
The underlying truth in radioactive decay is that on an individual basis, no unstable atom will have a predictable time until it will decay. We understand and characterize the decay of radionuclides on the basis of statistical analysis. Only by looking at a large number of atoms of a given isotope of a given element and counting the decay events over time can we quantify the decay rate. The term half-life is used to state (based on the statistics) when half of a given quantity of a substance will have undergone radioactive decay. Note that atoms are incredibly tiny things, and even if we have very tiny quantities of a given radioactive material, we'll have huge numbers of atoms of that material in the sample. The larger the number of atoms of material and the longer we count the decay events, the more accurate our half-life value will be. Having said all that, no one can predict when a given atom of any radionuclide will decay. Each is different, and that is the basis for the random nature of nuclear or radioactive decay.
Is there Radioactive decay in microwaves?
No. Radioactive decay is the breakdown of the nucleus of an atom due to its instability. This may emit radiation in the form of gamma rays or subatomic particles. Microwave "radiation" is the name given to electromagnetic waves in a certain range of frequencies. It differs from gamma rays, x-rays, and visible light only in frequency and energy.
When radioactive decays stop?
It will stop when there is nothing left to decay. There is basically no way to stop certain nuclides (isotopes) from decaying.
Radioactive decay can be affected by?
The rate of decay of a radioactive element cannot be influenced by any physical or chemical change. It is a rather constant phenomenon that appears to be independent of all others. The rate of decay is given by an element's half life, which is the amount of time for approximately half of the atoms to decay.
When does an isotope undergo Decay?
An atom of a given isotope will undergo radioactive decay whenever it feels like it. No joke. The nucleus of a radioactive isotope is unstable. Always. But that atom has no predictable moment of instability leading immediately to the decay event. We use something called a half life to estimate how long it will take for half a given quantity of an isotope to undergo radioactive decay until half the original amount is left, but this is a statistically calculated period. No one knows how long it will take a given atom of a radioactive isotope to decay, except that those with very short half lives will pretty much disappear relatively quickly.
Is radioactive decay the same as organic decay?
No, radioactive decay is not the same as organic decay. The basic difference between radioactive decay and organic decay is that in organic decay, chemical compounds break down and the biochemical structure of the subject changes. This is a natural process that any biological structures will undergo, or it could be induced. In either case, it represents a chemical change. In radioactive decay, the actual atomic nuclei of atoms will break down in some way, depending on the substance being considered. It is the unstable atomic nucleus of given isotopes of elements that undergoes the change, and this is a nuclear or atomic change.
What is given off by radioactive elements such as radium and Plutonium?
From these isotopes decay products are obtained and also ionizing radiations.
Is a delta particle a fast moving electron given off by a nucleus during radioactive decay?
No, a delta particle is not a fast moving electron given off by a nucleus during radioactive decay. The electron described here is a beta particle, and specifically a beta minus particle. It is given off in (no surprise) beta minus decay. A link to a related question can be found below.
