When an element decays what does it lose?
in alpha decay it loses a helium nucleus (2 protons, 2 neutrons)in beta decay a neutron converts to a proton and it ejects an electron and a neutrinoin gamma decay an excited nuclear state relaxes and a gamma photon is emittedin "k-capture" an inner electron is eaten by the nucleus converting a proton to a neutron and it ejects a neutrinothere are also a few other mechanisms.
A fast moving electron that is given off as a nuclear radiation is called?
Ok if what your looking for is an electron released from radioactive decay, it's a beta particle, which is created in beta decay =]In beta decay, a neutron in the nucleus spontaneously turns into a proton, an electron, and a third particle called an antineutrino. The nucleus ejects the electron and antineutrino, while the proton remains in the nucleus. The ejected electron is referred to as a beta particle. The nucleus loses one neutron and gains one proton. For example, a hydrogen-3 atom undergoing beta decay becomes a helium-3 atom.So simply, its a beta particle. But I also gave you a science explanation.Feel proud man =D
Radioactive decay occurs when the nucleus ejects the?
Radioactive decay occurs when the nucleus of unstable atoms eject protons, positrons or electron in order to attain a stable atomic structure. This yields new elements with reduced atomic number.
A transmutation involving the release of beta particles produces atoms whose atomic number has decreased by 2?
Alpha particles have two protons and two neutrons. since the atom just lost two protons, it's atomic number decreased two. It also decreased it's mass number by four because it lost two protons and two neutrons.
What is elimination in biology?
In biological terms, elimination is the process by which an organism ejects some unwanted substance from its body.
What new element is formed if magnesium-24 is bombarded with a neutron and then ejects a proton?
Sodium-24 would be formed if magnesium-24 is bombarded with a neutron and then ejects a proton. The neutron is absorbed to form magnesium-25, which then decays by emitting a proton to become sodium-24.
He decay of a neutron into a proton also ejects a small particle called a?
Beta Particle
How is it possible that negatively charged beta particles are emitted from a positively charged nucleus during nuclear decay?
An electron (negative particle) and an electron neutrino (neutral particle) are released when a neutron (neutral particle) changes into a proton(positive particle) therefore in order for neutral charge to create a positive particle it also has to create a negative particle to balance it out.As a significant amount of binding energy is released, the electron is ejected at high velocity as beta radiation while the much more massive nucleus containing the newly created proton recoils with very low velocity. The neutrino having almost no mass is ejected at almost the speed of light, but is nearly impossible to detect except by implication from the "missing momentum".Basically beta particles are ejected from the nucleus by conservation of momentum before and after the decay event.

When a neutron decays into a proton and releases an electron and an antineutrino how does the atom maintain an electron balance if it ejects the electron as beta radiation?
When beta minus decay occurs and a neutron is converted into a proton with the subsequent release of an electron and an antineutrino, the atom ends up with an "extra" proton in its nucleus. This changes the chemical identity of this atom. It also changes the proton-electron balance. Certainly this is understood or at least sensed in asking this question. The electron produced in the decay process leaves the nucleus at high energy; it doesn't hang around. That leaves the atom "short" an electron. Any atom that is in a state of electrostatic imbalance as the result of beta minus decay will "make arrangements" to balance itself by finding an electron somewhere. Let's jump to illustrate that point. There are a lot of "loose" electrons floating around on earth. They are everywhere. Most reside "in the ground" and just hang out there. A few will be floating around in the air, too. The reason for this is that there is a lot of static electricity being generated all around us every day. Something as simple as moving air will generate it. We even generate a lot ourselves just by moving around. But we generally don't notice it. But on a dry day, we can develop quite a static charge walking across a rug - which when then discharge by touching a door knob. Zap! Just because we don't get a shock most of the time doesn't mean we don't cause charge separation by moving. It's just that the charges are able to neutralize themselves quickly. Small static charges are in motion around us all the time. The electronics industry is painfully aware of static electricity. It damages components, and they spend millions of dollars training and equiping their workers and installing equipment in their plants to mitigate static electricity. Now back to answering the question. In the case of an atom that has undergone beta minus decay, it will "find" an electron somewhere within a short time because small amounts of charge are moving everywhere on a continuous basis. There will be an electron happening by in a very short time that this atom can "capture" and thereby neutralize itself. It does this with ease. Note that there is a bit more to this story than appears here. It involves quarks and the weak interaction. A link to the Wikipedia article on beta decay is provided.
What happens to molecules if they receive electromagnetic radiation?
They are excited and their energy increases and possibly ejects an electron and change their size and shape..They will often absorb part of the radiation; in that case, their energy will increase.

How does a nuclear reaction take place?
First nuclear reactions always involve the nucleus and except for K capture beta decay never involve any of the electrons around the nucleus.There are seven different types of ordinary nuclear reactions:fission, a massive nucleus splits into two lighter fragment nuclei (about 1/3 & 2/3 the mass of the original nucleus) and several free neutrons, fission can happen spontaneously in some isotopes (e.g. plutonium-240) but is usually triggered by the capture of a neutron, as fission always produces free neutrons it is possible to produce a neutron chain reaction to keep the process goingfusion, light nuclei join forming a heavier nucleus, this reaction can only happen under conditions of very high temperature and pressure (causing the nuclei to be fully ionized, traveling at high velocity, and pressed tightly together) it is very hard to to get started and keep going (except deep inside stars) Note that fusion is the only one of these seven nuclear reactions that is affected in any way by the temperature or pressure of the environment it happens inalpha decay, a nucleus spontaneously ejects a helium nucleus (i.e. alpha particle)beta- decay, a neutron in the nucleus spontaneously transforms into a proton and the nucleus ejects an electron and an electron antineutrinobeta+ decay, a proton in the nucleus spontaneously transforms into a neutron and the nucleus ejects an positron and an electron neutrinoK capture beta decay, a proton in the nucleus spontaneously transforms into a neutron and the nucleus captures an electron from the innermost (i.e. K) electron shell and ejects an electron neutrinogamma decay, a nucleus in a metastable (i.e. excess energy) state spontaneously relaxes its proton and/or neutron shells to a lower energy state and ejects a gamma photon with an energy equal to the energy lost in the nucleusHowever if you include other subatomic particles not present in ordinary matter (e.g. muons, antimatter particles, strange particles) a much wider and more confusing variety of nuclear reactions can happen that are beyond the scope of the original question. I will only mention one of these nuclear reactions: muon catalysed cold fusion. This is interesting because it permits the fusion nuclear reaction to happen at ordinary room temperature.In muon catalyzed cold fusion the electrons around hydrogen nuclei are replaced with muons (particles identical to electrons in every way except that they have 200 times the mass), being much more massive than electrons their orbitals are much smaller. So much smaller that the nuclei can come close enough to each other at ordinary room temperature that the nuclei can fuse! The fusion energy release causes the product nucleus to lose its muons and become ionized. This process is called "muon catalyzed" because these free muons can now replace electrons around fresh hydrogen nuclei, repeating the nuclear reaction over and over without requiring any additional muons. The only problem with muon catalyzed cold fusion is that the muons required to begin this nuclear reaction are very expensive to produce.
