Isotopes

Isotopes are not gases. Isotopes are variants of a particular chemical element that have the same number of protons but different numbers of neutrons. Gases refer to the state of matter in which a substance spreads out to fill its container.

Inject the gaseous mixture of the three isotopes into a mass spectrometer. This is a machine which determines the composition of different elements in a compound. In this case, this machine is going to determine the percentage abundance of each of the isotopes. You will see lines on the spectrum produced. Basically, how the mass spectrometer works is that the isotopes are ionized to form X+ ions. Then, the ions are accelerated to very high speeds using an electric field. After this, they are passed through a strong magnetic field, which makes the electrically charged ions deviate to go on a curved path. The mass of the ion(in this case, different isotopes have different ions) determines how much it deviates. There is a detector at the end of the machine which detects this, and in turn, the percent composition of different isotopes.

Deuterium is a hydrogen isotope with a mass of 2, consisting of one proton and one neutron in its nucleus, in addition to one electron orbiting the nucleus. It is used in nuclear fusion research and some industrial processes.

A = mass number

z = atomic number

so this one is a Ni isotope with a mass of 64

Technetium-99m exists as a metastable isomer, meaning it is in a higher energy state but has a relatively long half-life compared to other technetium isotopes. It decays by emitting gamma radiation, making it useful for medical imaging procedures.

The four isotopes of strontium are strontium-84, strontium-86, strontium-87, and strontium-88. The most abundant and stable isotope is strontium-88, making up about 82.6% of naturally occurring strontium.

Chlorine-35 isotope has a higher abundance than Chlorine-37. Chlorine-35 makes up about 75.77% of naturally occurring chlorine atoms, while Chlorine-37 makes up about 24.23%.

Geologists can determine the ages of rocks and fossils by analyzing the isotopes found in them. Radiation from certain isotopes can be used to treat cancer and to kill bacteria that cause food to spoil. Radioactive isotopes can also be used as labels or "tracers" to follow the movements of substances within organisms.

Atoms have the same number of protons, but different numbers of neutrons. This means that the mass number changes, even though the atomic number stays the same. Therefore, the two atoms will still belong to the same element, even though their number of nucleons vary.

A fissile isotope is one that can undergo fission when struck by a neutron, releasing energy and more neutrons that can then cause further fission reactions. This property is essential in nuclear reactors and nuclear weapons. Examples of fissile isotopes include uranium-235 and plutonium-239.

If an isotope is fissionable, it means that it can undergo nuclear fission, a process where the nucleus of an atom splits into smaller parts, releasing a large amount of energy. This property is important for nuclear reactors and nuclear weapons.

Carbon-11 is often used in positron emission tomography (PET) scans to locate brain tumors. This isotope can be attached to a tracer substance that is injected into the bloodstream, allowing the PET scan to detect the accumulation of the tracer in areas with high metabolic activity, such as tumors in the brain.

Deuterium, that is hydrogen with one proton and one neutron in the nucleus, exists as a small proportion of all natural hydrogen, so in the oceans there is a huge amount of it as a potential fuel. Many isotopes that are produced artificially in nuclear recators are useful in medicine and industry. For example in medicine isotopes can be used to trace the passage of food through the human system (the Barium meal), and can also be used in radiotherapy to deliver a prescribed dose of radiation to a particular organ for cancer treatment. Isotopes with half lives of a suitable amount can be left in the body if required as they become inactive after a while. In industry powerful gamma isotopes are often used in such practices as examining thick plates and welds for defects.

Which isotope of what element? We need a little more information here in order to be able to help you. However, the most common isotope of Oxygen has 8 neutrons. I hope this answers the question. If not, please try resubmitting with more information.

An isotope is unstable if the ratio of protons to neutrons in its nucleus is not optimal. This imbalance can lead to excessive nuclear energy, causing the isotope to decay in order to achieve a more stable configuration. Factors like excess energy, suboptimal nuclear forces, and high neutron-to-proton ratios contribute to the instability of isotopes.

None, no element beyond lithium can have a stable isotope with as few as 3 neutrons. If by some happenstance a uranium nucleus did form with as few as 3 neutrons (this would be U95) it would instantly burst apart in a flash of protons before it could even be detected.

Isotopes do not stop decaying. The process of radioactive decay continues until the isotope reaches a stable state, which could be a different isotope or a non-radioactive element. The rate of decay can vary depending on the specific isotope.

Radioactive isotopes are important because they can be used as tracers in medicine and industry, and in dating rocks and fossils. The concept of half-life is important because it allows scientists to predict how long it will take for a radioactive material to decay to half its original amount, which is crucial for understanding processes like nuclear decay and radioactive dating.

Isotopes depend of the number of neutrons in the nucleus.

The number of protons will always remain the same for that particular element. The number of neutrons may vary because they do not affect the charge, but rather its weight. This is why we have peculiar numbers for the average atomic mass, because some elements have different isotopes and based on how common they are will affect its average atomic mass.

they both spontaneously emit radiation in the form of alpha, beta, or gamma rays. This radiation can damage living tissue and increase the risk of cancer if exposure is prolonged. Both substances are radioactive and undergo radioactive decay over time.

The ionization energy of isotopes is the same because isotopes have the same number of protons in their nucleus, which determines the ionization energy. Isotopes differ in the number of neutrons they possess, but neutrons do not contribute significantly to the ionization energy compared to protons.

An isotope is not a chemical property; rather, it refers to different forms of an element that have the same number of protons but different numbers of neutrons. Isotopes can affect the physical properties of an element, such as its mass and stability, but they do not change its chemical properties.

No, an isotope is an atom with the same number of protons but a different number of neutrons. A positive charge on an atom would indicate it has either lost electrons or gained protons.

The parent isotope is the original radioactive isotope that undergoes decay to form the daughter isotope. The daughter isotope is the stable isotope that is formed as a result of the radioactive decay of the parent isotope.

No, that's an ion. An isotope is an atom of the same element with a different number of neutrons.
