What do you call a atom that decays?

When an atom decays to its ground state, it emits a photon of green light. When an atom decays to an intermediate state, the light emitted is red.

unstable, radioactive

Radioactivity

6 Li 3

If an atom that emits a green proton when it decays to its ground state decays to an intermediate state instead it will emit a proton that is yellow/orange/red. The reason is that it will be a lower energy proton emitted and lower energy waves correspond to longer wavelengths like the ones that make up these colors.

Technically an atom doesn't decay. Radiation occurs when there are considerably more neutrons in an atom than is necessary, and the atom emits the neutron.

a beta particle

Tritium decay to helium-3.

The atom is still 24Na (sodium-24) because gamma emission does not change the nucleus of the atom.

Waste that decays is called biodegradable waste. Dead plant material that has decayed (as in compost) is called humus.

entropy

it is unstable and decays to another element

Light of a longer wavelength than green light, like, for example, red light assuming the initial state is the same in both cases.

Such an atom would be called "radioactive." A radioactive substance is not something you want to be near.

That's what an atom emits when it decays.

according to google XD, this is the radioactive atom that decays to product a daughter isotope

In beta- decay, a neutron becomes a proton, leaving an atom of 24Mg (magnesium, which has 12 protons compared to 11 for sodium)

The universe is chaotic. As every atom was formed, eventually every atom will fall apart. Every atom decays, although some at very very slow rates.

radioactive decay occurs when a large atom begins to fall apart due to its size

Though the electron itself is not present in the nucleus of an atom, the elementary particles that make up the electron are present inside the neutron. In other words, a neutron is made up of an electron and a proton. How do we know this? Because when a neutron decays, it slowly decays into a proton and an electron. It's a cycle.

232U alpha decays to 228Th. Thorium-228 is the daughter product of the alpha decay of uranium-232.

The question doesn't really make sense but with a guess at it's meaning I would say oxygen.

Really, it is the whole thing. An atom decays because the nucleus is unstable. The nucleus contains protons and neutrons, and only certain combinations of the numbers of each are stable. When a radioactive atom decays, it can do a number of different things. Best known by ordinary people, possibly, is nuclear fission, in which the whole atom breaks apart to become two atoms. In the process various pieces of the atom also are released…

Decays to another element with less protons, lower atom number.

The same atom of strontium-90 (90 Sr) The release of gamma radiation doesn't cause any change to the number of protons and neutrons.

Alpha radiation is when the nucleus of an unstable element releases an alpha particle (two protons and two neutrons; the equivalent of the nucleus of a helium atom)due to the weak nuclear force. The resulting atom is now a different element because the number of protons it has determines which element it is. Beta radiation (β− ) is when a neutron in an unstable atom with an excess of neutrons turns into a proton because…

the aTOM of protactinium 234 formed

Number of alpha particles = (238-106)/4 = 32/4 = 8

neutral atom.

Henry Becquerel is famously known for his contribition to radiation and radioactive decay. There is a term known after him called the Becquerel which is a measure of radioactive decays of a substance per second. In other words, it is the activity of the substance - the rate at which it decays

Some possible decays: - U-231------------Pa-231 (by electron capture) - U-229------------Pa-229 (emission of a beta particle) - U-228------------Pa-228 (by electron capture)

A molecule containing one Carbon atom and three Oxygen atoms, CO3, is called Carbon Trioxide. It is unstable and normally decays into carbon dioxide and oxygen.

Because the less protons are in an atom the quicker it decays.

Some possible decays: - U-231------------Pa-231 (by electron capture) - U-229------------Pa-229 (emission of a beta particle) - U-228------------Pa-228 (by electron capture)

You call a substance with only one type of atom, an element.

you call it an ion

Negative atom

Negative beta (electron) decay; in which the mass number remains constant) and the atomic number of daughter atom in higher than the parent atom by one.

Gold never decays by alpha emission, it either decays by -beta, +beta, K capture, or gamma emission depending on isotope. Natural gold is isotopically pure gold-197, which is stable.

The daughter nuclide is the atom or atoms that result when a parent nuclide decays through emission of ionizing radiation or through fission.

Well...they DON'T use that kind of isotope. They use an isotope (Technetium-99) which decays into the slowly-decaying radioisotope Technetium-98...and they use this because, with a medically-useful half-life of a little over six hours, the patient is exposed to radiation for only as long as he or she needs to be.

A thorium-234 atom has 90 protons and 144 neutrons. It has a half-life of 24.5 days. When it decays it emits a beta particle and a gamma ray, leaving behind a protactinium-234 atom.

Nucleus of the standard isotope of carbon atom has 6 protons and 6 neutrons (carbon 12). Other Isotopes of carbon atoms are also possible, such as C14, which has 8 neutrons, and decays by beta particle emission into nitrogen.

A 'monatomic' atom.

An atom of a different element.

Carbon-14 decays by emitting an electron and electron antineutrino. The resulting atom is Nitrogen-14. The energy of the emission is 0.156476 MeV.

An electrically charged atom is called an ion.
