What is a nuclide? Write out the nuclide symbol for a nuclide with an atomic number equal to 53 if the number of neutrons it contains is 79. What is an isotope symbol? What is the isotope symbol for cobalt-60? What is the isotope symbol for phosphorus-32?
Isotope and nuclide are closely related terms. When one speaks of isotopes, they are referring to the set of nuclides that have the same number of protons. Nuclide is a more general term, referring to a nuclear species that may or may not be isotopes of a single element. Examples: ...
An isotope is a variant on an element that has a different atomic weight from other variants. Except for the commonest form of hydrogen— which has only a proton— every atomic nucleus in normal matter is made of both protons and neutrons. Isotopes of a given element have the same number...
What is the most common isotope of argon? Isotopes Explained: Elements are classified by the number of protons in the nucleus of the atom. However, there is no set rule for how many neutrons can be in the atom's nucleus. Because this number can vary, we classify the different, naturally...
Venus is Earth's closest planetary neighbour and both bodies are of similar size and mass. As a consequence, Venus is often described as Earth's sister planet. But the two worlds have followed very different evolutionary paths, with Earth having benign surface conditions, whereas Venus has a ...
The most common carbon isotope is carbon-12. Its name signifies that its nucleus contains six protons and six neutrons, for a total of 12. On Earth, carbon-12 accounts for almost 99 percent of naturally occurring carbon. Scientists use atomic mass units, or amu, to measure the mass of el...
An isotope scan is a medical procedure that produces pictures of the inside of the body. During the procedure a radioactive substance is ingested. This substance migrates to the area of the body being scanned. A special camera and computer is then used to create pictures. The isotope, or ...
Lithium has an atomic mass of 6.96. There are only two natural isotopes of Li: Li-6 and Li-7. What is the percent of each isotope present? Lithium has two naturally occurring isotopes, 6-Li and 7-Li, with masses of 6.015 amu and 7.016 amu...
