Isotopes

The formula is Atomic Mass (rounded to the nearest whole number) minus the Atomic Number.

This works because Protons and Neutrons have virtually the same mass, and electrons virtually none. As well as the Atomic Number being equal to the amount of Protons.

Essentially:

Protons + Neutrons - Protons = Neutrons. Basic Prealgebra.

So to find the amount of Neutrons in Erbium:

Erbium's Atomic Mass rounded (167) - Erbium's Atomic Number (68) = approx. 99 Neutrons

Carbon-12 (98.93%), Carbon-13 (1.07%), and Carbon-14 (1 PPT) all occur naturally. However, Carbon-14 is radioactive (halflife 5,730±40 years) and is being produced only high in the atmosphere by bombardment of nitrogen gas by cosmic rays.

1. Radium has 45 isotopes and nuclear isomers.

2. Radium has no known today allotropes.

Plutonium has no natural isotopes. All plutonium isotopes are artificially produced through nuclear reactions.

Barium has seven isotopes, with atomic masses ranging from 130 to 138. The most abundant isotope of barium is Barium-138, making up about 71% of naturally occurring barium. Barium-137 is a radioactive isotope with a half-life of about 2.5 minutes.

Yes, even though they do emit ionizing radiation. The amount of radiation emitted from a smoke detector is about 1 hundredth of a millirem per year. The background radiation from radioactive isotopes in the ground is about 300 millirem per year. So the ground your standing on right now is exposing you to more radiation then your smoke detector ever will.

An isotope of zirconium will have protons, neutrons, and electrons. Zirconium typically has 40 protons and varying numbers of neutrons in its isotopes. Electrons surround the nucleus of the atom, balancing the positive charge of the protons.

70Ge (21.23%) - 38 neutrons
72Ge (27.66%) - 40 neutrons
73Ge (7.73%) - 41 neutrons
74Ge (35.94%) - 42 neutrons
76Ge (7.44%) - 44 neutrons

Candu reactors have traditionally used natural uranium, which contains 0.7 percent U-235, which is the fissile isotope that produces all the nuclear fission energy. Proposals have been made that Candus could use fuel that has been discharged from light water reactors and might still contain about 0.9 percent U-235, or could even use fuel made from depleted uranium (mostly U-238) together with fissile plutonium available from dismantled nuclear weapons, but I don't think such proposals have reached the stage of implementation. For one thing, Canada doesn't have any nuclear weapons, so it would require some fuel manufacture to be set up in the US to make this fuel, or to utilise US spent fuel. There is plenty of this in US storage but no route for using it to make Candu fuel, which is of different dimensions and assembly details. However this might conceivably be done in the future.

Frederick Soddy discovered isotopes through his collaboration with Ernest Rutherford in studying radioactivity. They observed that certain elements had multiple forms with different atomic weights but similar chemical properties, leading to the concept of isotopes. Soddy coined the term "isotope" in 1913 to describe these different forms of elements.

The stable isotope formed by the breakdown of a radioactive isotope is called a daughter isotope. This process is known as radioactive decay, where a radioactive isotope transforms into a stable daughter isotope through the emission of particles or energy.

Carbon 12 and Carbon 13 are stable. All other isotopes of carbon are unstable and radioactive

The length of time required for half of a sample of radioactive material to decay

During nuclear decay, an isotope of an element changes by emitting radiation, such as alpha or beta particles, or gamma rays. This process results in the isotope transforming into a different element or a different isotope of the same element. The change is necessary to achieve a more stable configuration, typically by adjusting the number of protons and neutrons in the nucleus.

Isotopes can be used as tags by incorporating them into molecules or compounds that are then added to a sample of interest. The presence and abundance of the isotope can be detected using specialized techniques like mass spectrometry, allowing researchers to track the movement or behavior of the tagged molecules within the sample. This is commonly used in biological, environmental, and chemical research.

This is a really difficult question to answer... 1. There is no such thing as a MgO solution. Magnesium oxide reacts vigorously with water to form Mg(OH)2. 2. Mg(OH)2 is insoluble, with a Ksp of 5.61x10-12. So it doesn't form a solution with water either, it forms a suspension. Ever heard of Milk of Magnesia? That thick white liquid is a suspension of magnesium hydroxide in water. 3. Is the question asking for a concentration or the actual number of ions? The former is answerable using the Ksp. The latter is not because you would need to not only calculate the concentration, but also know the volume of the solution. So depending on what you are looking for, repost your question and I will take a shot at it.

chemical properties. False. Isotopes of an element have the same chemical properties because they have the same number of protons and electrons, which determine the element's chemical behavior. The differences between isotopes lie in their nuclear properties, such as atomic mass and stability.

Carbon-14 is the isotope commonly used to determine the age of bones and other organic material. This radioactive isotope is incorporated into living organisms and decays at a known rate, allowing scientists to estimate the age of the bone based on the amount of carbon-14 remaining.

Yes, butane does have isotopes. The most common isotopes of butane are carbon-12 and carbon-13. Isotopes of butane can have varying masses due to differences in the number of neutrons in the nucleus.

Yes, magnesium does have isotopes. There are three stable isotopes of magnesium: magnesium-24, magnesium-25, and magnesium-26, with magnesium-24 being the most abundant. Additionally, there are a few unstable isotopes of magnesium that have been synthesized in laboratories.

The cost of an isotope bone scan test in India can vary depending on the location and healthcare provider. On average, the cost can range from 5000 to 10000 Indian Rupees. It is recommended to check with different diagnostic centers or hospitals to compare prices and services.

The most common isotope of selenium is selenium-80, which makes up about 50% of naturally occurring selenium.

1. Hydrogen has three isotopes: protium (1H), deuterium (2H), and tritium (3H).
2. Carbon has two stable isotopes: carbon-12 (12C) and carbon-13 (13C), along with a radioactive isotope, carbon-14 (14C).
3. Oxygen has three isotopes: oxygen-16 (16O), oxygen-17 (17O), and oxygen-18 (18O).

Each isotope's mass is multiplied by its percent abundance to account for the contribution of each isotope to the overall average atomic mass of an element. This calculation ensures that the final average atomic mass reflects the weighted average of the masses of all isotopes based on their abundance in nature.
