What are isotopes one sentence?

isotope, one of two or more species of atoms of a chemical element with the same atomic number and position in the periodic table and nearly identical chemical behaviour but with different atomic masses and physical properties. Every chemical element has one or more isotopes.

What is Isotopy and examples?

Isotopes can be defined as the variants of chemical elements that possess the same number of protons and electrons, but a different number of neutrons. For example, uranium-235 and uranium-239 are two different isotopes of the element uranium.

What do you mean by isobars?

Definition of isobar 1 : an imaginary line or a line on a map or chart connecting or marking places of equal barometric pressure. 2 : one of two or more atoms or elements having the same atomic weights or mass numbers but different atomic numbers.

How do you determine isotopes?

Subtract the atomic number (the number of protons) from the rounded atomic weight. This gives you the number of neutrons in the most common isotope. Use the interactive periodic table at The Berkeley Laboratory Isotopes Project to find what other isotopes of that element exist.

Why do isotopes exist?

Isotopes are atoms of the same element with different masses. They get these different masses by having different numbers of neutrons in their nucleii. Isotopes of atoms that occur in nature come in two flavors: stable and unstable (radioactive).

What are 3 uses of radioactive isotopes?

Different chemical forms are used for brain, bone, liver, spleen and kidney imaging and also for blood flow studies. Used to locate leaks in industrial pipe lines…and in oil well studies. Used in nuclear medicine for nuclear cardiology and tumor detection. Used to study bone formation and metabolism.

What is Isobar give an example?

Isobars are atoms (nuclides) of different chemical elements that have the same number of nucleons. Correspondingly, isobars differ in atomic number (or number of protons) but have the same mass number. An example of a series of isobars would be 40S, 40Cl, 40Ar, 40K, and 40Ca.

Why do isobars exist?

Atoms of chemical elements having same atomic mass but a different atomic number are called Isobars. The sum of the number of protons and neutrons together form the atomic mass. Therefore, they are always different chemical elements having same atomic masses. Thus, isobar has different chemical properties.

Why is the mass number different in two isotopes?

Atoms of the same element have the same number of protons, which is called the atomic number. Different isotopes of an element have different numbers of neutrons. As a result, they also have different mass numbers, which is the number of protons plus the number of neutrons.

Which field is the chosen isotope most useful?

Radioactive isotopes have many useful applications. In particular, they are central to the fields of nuclear medicine and radiotherapy. In nuclear medicine, tracer radioisotopes may be taken orally or be injected or inhaled into the body.

Why can’t certain isotopes exist?

Some elements do not have any stable isotopes, such as curium. These only exist on Earth because they are created in nuclear reactors, nuclear explosions, or particle accelerators. Some unstable isotopes exist naturally on Earth because they have a very long half-life.

Which is the best definition of an isotope?

Science definitions for isotope. One of two or more atoms that have the same atomic number (the same number of protons) but a different number of neutrons. Carbon 12, the most common form of carbon, has six protons and six neutrons, whereas carbon 14 has six protons and eight neutrons.

What happens if you write with incorrect grammar?

If you write with incorrect grammar, your readers will not forgive you for this, and they will start giving bad reviews that can hurt your name. Some of your readers are in actual your competitors who are in search of any mistake by you so that they get a chance to prove themselves better.

What kind of Errors does check grammar detect?

The mistakes that check grammar detects will be indicated by highlighting them so that it is easy for you to figure out what errors you frequently make. The grammar check will detect punctuation, grammar, spelling and sentence structure errors.
