What are four characteristics of isotopes?

Which of the following are the correct characteristics of isotopes of an element? (i) same atomic mass (ii) same atomic number. (iii) same physical properties (iv) same chemical properties.

What characteristics do isotopes share?

Isotopes of an element share the same number of protons but have different numbers of neutrons.

What are the three properties of isotopes?

(i) isotopes of an element have the same atomic masses. (ii) isotopes of an element have the same atomic number. (iii) isotopes of an element show the same physical properties.

Do isotopes have different characteristics?

The chemical properties of different isotopes are nearly identical. However, the physical properties of isotopes such as mass, melting or boiling point, density, and freezing point are all different. The physical properties of any isotope are primarily determined by its mass.

What are 5 examples of isotopes?

Examples of radioactive isotopes include carbon-14, tritium (hydrogen-3), chlorine-36, uranium-235, and uranium-238. Some isotopes are known to have extremely long half-lives (in the order of hundreds of millions of years). Such isotopes are commonly referred to as stable nuclides or stable isotopes.

How do you identify isotopes?

Which of the following are the characteristics of isotope of an element?

Isotopes of an element have same atomic number but different atomic masses. They show same chemical properties but different physical properties. Was this answer helpful?

Why do isotopes have different physical properties?

Isotopes of an element have different physical properties because they have different mass numbers. Chemical properties of different isotopes are almost similar. When it comes to physical properties of isotopes including mass, melting or boiling point, density, and freezing point, they are all different.

Which of the following best describes isotopes?

Which of the following best describes an isotope? Structurally variant atoms, which have the same number of protons (and electrons), but differ in the number of neutrons they contain.

What do isotopes tell us?

Isotopic analysis can be used to understand the flow of energy through a food web, to reconstruct past environmental and climatic conditions, to investigate human and animal diets, for food authentification, and a variety of other physical, geological, palaeontological and chemical processes.

What are some characteristics of radionuclides?

A radionuclide (radioactive nuclide, radioisotope or radioactive isotope) is a nuclide that has excess nuclear energy, making it unstable.

  • 6.2 Beta emission only.
  • 6.3 Alpha emission only.
  • 6.4 Multiple radiation emitters.

How do the number of protons and electrons relate in an isotope?

To find the number of electrons, add the opposite of the charge imbalance to the number of protons. For example, if an isotope has a -3 charge, as with phosphorus (atomic number 15), then the number of electrons is three greater than the number of protons.

How are isotopes used in forensic science?

For several years, forensic scientists have been able to use isotopes found in human hair as markers that can indicate a region of the country where a person was living because many water supplies have unique isotopic signatures that are captured in hair.

Why do isotopes decay?

Every atom seeks to be as stable as possible. In the case of radioactive decay, instability occurs when there is an imbalance in the number of protons and neutrons in the atomic nucleus. Basically, there is too much energy inside the nucleus to hold all the nucleons together.

What are stable and unstable isotopes?

The stable isotopes have nuclei that do not decay to other isotopes on geologic time scales but may themselves be produced by the decay of radioactive isotopes. Radioactive (unstable) isotopes have nuclei that spontaneously decay over time to form other isotopes.
