Does silicon have any isotopes?

Yes: Naturally occurring silicon contains isotopes with mass numbers 28, 29, and 30 in order of decreasing abundance. As with almost any element, many artificial, radioactive isotopes are also known.

Give an example of an isotope used in dating old objects?

cardon-14 by the use of carbon dating which is a process in which they use the half life of carbon to calculate the date of an object

How many isotopes of gallium are there?

There are two stable isotopes of gallium: gallium-69 and gallium-71. Additionally, there are several radioactive isotopes of gallium, but they are unstable and decay over time.

Which noble gas has a radioactive isotope?

Radon is a noble gas and is radioactive. All of the other noble gasses have at least some synthetic radioactive isotopes. Radioactive isotopes of both krypton and argon exist in nature in trace quantities.

How is isotope eliminated from the body?

isotopes are eliminated from the body the same way any other atom is.

Ions, which is the next closest thing I think you may mean, are excreted through urine (since they can dissolve in water so well).

Are radioactive isotopes electrically unbalanced?

No, radioactive isotopes are not necessarily electrically unbalanced. Radioactive isotopes have unstable nuclei that undergo radioactive decay, which can result in the emission of radiation such as alpha, beta, or gamma particles to achieve a more stable state. This decay process does not impact the electrical balance of the atom.

The mass of the mixture of the isotopes for an element?

The mass of a mixture of isotopes for an element is a weighted average of the masses of each isotope, calculated based on the isotope abundances. The formula for calculating the average atomic mass is: (mass of isotope 1 x abundance of isotope 1) + (mass of isotope 2 x abundance of isotope 2) + ...

How does one isotope differ from another isotope of the same element?

Isotopes of an element have a different number of neutrons. For example Uranium-235 and Uranium-238 look chemically identical but 238U atom is slightly more massive due to the three extra neutrons.

5 examples of isotope and its uses?

Isotopes are Chemical elements which will be having the same number of protons but different number of neutrons. Few examples for Isotopes are: Carbon, Uranium, Helium. Isotopes are used in Radioactivity, Radiation Oncology, Radiometric dating.

What is isotope oxygen is?

Isotope oxygen is a variant of the element oxygen that has a different number of neutrons in its nucleus compared to the most common form of oxygen (oxygen-16). Isotopes of oxygen include oxygen-18 and oxygen-17.

Which isotope of uranium is used in atomic reactors?

U-235 is the fissile isotope that produces the reactor power output in new fuel. During operation some of the U-238 is converted to plutonium which also contributes to the power of the reactor, an increasing amount as the U-235 is used up.

Give an example of isotope?

For example uranium has 3 natural isotopes, all radioactive U-234, U-235, U-238.

Also hydrogen has 3 natural isotopes: H-1, H-2 (deuterium), H-3 (tritium) and 3 artificial isotopes; H-4, H-5, H-6.

All the chemical elements has isotopes, stables or radioactive, naturals or artificial.

like oxygen have 3 isotopes O-16,O-17,O-18.

lithium have 2 isotopes like Li-6,Li-7.and many other like magnesium have 3 natural isotopes,Mg-24,Mg-25,Mg-26.

If the isotope is given what is the formula?

Isotopes are different forms of the same atom with different numbers of neutrons. For example, normal carbon is carbon-12, which has 6 protons, 6 neutrons. Carbon-14 has 2 extra neutrons making it heavier. But they have the same numbers of electrons and so react and form compounds in the same way - so the formula of methane CH4 or carbon dioxide CO2 is the same. If you want to be very specific you can indicate the labeled position with a superscript, thus: 13CH4 or CH313CH2OH indicate methane with the carbon-13 isotope or ethane labeled with carbon-13 at the alpha position, respectively.

What isotopes always have the same element?

Isotopes are variations of an element. Isotopes of one element always have the same number of protons because it's the number of protons that define the element. Isotopes of an element have the same number of electrons which will equal the number of protons. (That ignores atoms that are in the form of ions.)

Different isotopes of the same element have different numbers of neutrons. The variations in the number of neutrons make the mass of atoms different but they do not change the element nor do they change the chemical properties of the element.

Some isotopes of an element can be radio-active, that is, they are unstable and can emit an alpha or beta particle or a gamma ray. As an example, carbon has 6 protons and most atoms have 6 neutrons. A few carbon atoms have 8 neutrons with a mass of 14. It is known as "Carbon 14" and is radio active. That is because the nucleus can emit a beta particle and in doing so, the atom actually changes to a nitrogen atom.

The stability of an isotope nucleus depends on the?

The stability of an isotope nucleus depends on the balance between the strong nuclear force, which holds protons and neutrons together, and the electromagnetic force, which repels protons due to their positive charge. Isotopes with too many or too few neutrons compared to protons may be unstable and undergo radioactive decay to achieve a more stable configuration.

Do isotopes lose electrons?

The term isotope is used to indicate the different varieties of a single element, based upon variations in the number of neutrons in the nucleus. Every atom can be described as an isotope if we specify the number of neutrons. And every atom can lose electrons (a process officially called ionization). There is no relation between the number of neutrons and the loss of electrons.

What determines the different isotopes of an atom?

The isotopes of an atom are defined by the number of neutrons their nuclei have for their fixed number of protons. However, I wouldn't say that neutrons are solely responsible for the presence of isotopes because isotopes also depend on the existence of many other particles such as protons, quarks and gluons. Neutrons certainly are responsible for the way we label isotopes, though.

Working models on chemistry for class 9?

Well a chemistry class for a freshman year would basically be chemical problems and lots of algebra work (since most 9th graders haven't taken geometry yet) If you can avoid taking chemistry freshman year, I would recommend it. But

Nickel has 5 isotopes what is the relationship of these isotopes?

The isotopes of nickel share the same number of protons (28) but differ in the number of neutrons in their nuclei, resulting in different mass numbers. Each isotope of nickel has a different abundance in nature, with nickel-58 being the most common.

How do you shorten the half-life of a radioactive element?

Making any change in the half-life of an isotope of any element is generally something that lies outside our abilities. A very few radioactive materials have demonstrated a change in their half-lives when bathed in intense magnetic fields. Generally, however, the half-life on a given radionuclide is not something that can be changed. A number of experiments have been conducted wherein investigators have deliberately sought to influence radioactive half-life, but in all but the rarest cases, radionuclides are sublimely resistant to having their half-lives changed.

Radioactive isotopes are used to determine?

The age of rocks and minerals through radiometric dating, the presence of tumors in the body through imaging techniques like PET scans, and the effectiveness of treatments for cancer through radiation therapy.

The most common isotope of strontium is?

Strontium-88

It is the closest to the Strontium atomic mass.

What is nuclear isotopes?

A radioactive isotope is a form of an element that is unstable and eventually decays into a different element. For example, most Carbon has 6 protons and 6 neutrons, and is stable. This is called Carbon12.

Carbon14 with 6 protons and 8 neutrons, is unstable and decays by releasing a beta particle from its nucleus to become a stable isotope, Nitrogen14. which has 7 protons and 7 neutrons.
That refers to an isotope that is unstable - the atoms will decay after a while.

What are Nuclear Isotopes?

Nuclear Isotopes are different types of atoms of the same chemical element having a different number of neutrons, which that chemical element is involved in the nuclear industry (e.g.: Uranium-235, Astatine-211, Americium-241). Most are very unstable, but a handful of them naturally occur on Earth (e.g.: Iodine-131, Carbon-14, Caesium-137)

Nuclear Isotopes are radioactive and should be treated with extreme care! No joke here when handling even the safest of nuclear isotopes (just in case you were wondering, Uranium-235 or Depleted Uranium, is the safest nuclear isotope).
