Definition of isotope. Atoms with the same number of protons in the nucleus can have different. numbers of neutrons. Atoms with the same number of protons but different. number of neutrons are isotopes of the same element.
What are types of isotopes?
There are two main types of isotopes, and these are radioactive isotopes and stable isotopes. Stable isotopes have a stable combination of protons and neutrons, so they have stable nuclei and do not undergo decay.
What is stable isotope?
Stable isotopes are non-radioactive forms of atoms. While deuterium H-2, an isotope twice as heavy as hydrogen, is predominantly used in nutrition research, nitrogen-15 is the most common stable isotope used in agriculture.
What is an isotope simple definition?
An isotope is 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 behavior but with different atomic masses and physical properties. Every chemical element has one or more isotopes.
How would you define an isotope?
What is an isotope symbol?
Isotope Notation Isotopes can also be defined in standard, or “AZE”, notation where A is the mass number, Z is the atomic number, and E is the element symbol. The mass number “A” is indicated with a superscript to the left of the chemical symbol “E” while the atomic number “Z” is indicated with a subscript.
What can isotopes tell us?
Isotope analysis can be used by forensic investigators to determine whether two or more samples of explosives are of a common origin. Most high explosives contain carbon, hydrogen, nitrogen and oxygen atoms and thus comparing their relative abundances of isotopes can reveal the existence of a common origin.
What are isotopes uses?
Radioactive isotopes have many useful applications. In medicine, for example, cobalt-60 is extensively employed as a radiation source to arrest the development of cancer. Other radioactive isotopes are used as tracers for diagnostic purposes as well as in research on metabolic processes.
What is called isotope?
An isotope is 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 behavior but with different atomic masses and physical properties.
How do you define isotopes?
Isotopes are atoms of the same element that have different numbers of neutrons but the same number of protons and electrons. The difference in the number of neutrons between the various isotopes of an element means that the various isotopes have different masses.
What does the Ninth Amendment mean in simple terms?
Ninth Amendment. The Ninth Amendment to the U.S. Constitution reads: The enumeration in the Constitution, of certain rights, shall not be construed to deny or disparage others retained by the people.
What is the meaning of isotope in Thesaurus?

Does the Ninth Amendment enunciate any substantive rights?
By itself, one court held, the Ninth Amendment does not enunciate any substantive rights. Instead the amendment serves to protect other fundamental liberties that are implicit, though not mentioned, in the Bill of Rights (Rothner v. City of Chicago, 725 F. Supp. 945 [N.D.
