=Unlike stable isotopes such as Carbon- 12 or oxygen- 1, radioisotopes spontaneously change into other isotopes over time.=
Primarily, isotopes differ in the number of neutrons in the nucleus. Secondarily, because some combinations of protons and neutrons produce an unstable nucleus, they may differ by being radioactive.
Differences in IsotopesThey have different numbers of neutrons and therefore different mass numbers.
Isotopes differ in the number of neutrons. All atoms are neutral - they always contain the same number of protons (positive) as electrons (negative). If they lose or gain electrons, they become ions. If they lose or gain protons (as in radioactive decay), they become a different element. An element is defined by its atomic number, which is the number of protons. Atoms may differ in their atomic mass. The difference is due to differing numbers of neutrons. The atomic mass on the periodic chart is the proportional average of all the naturally occurring isotopes. To determine how many neutrons in an atom, subtract the atomic number from the atomic mass.
They are called isotopes,
The number of neutrons is different.
Isotopes of the same element differ in the number of neutrons. Isotopes have different physical properties but similar chemical properties.
No they don't have. Isotopes of an element differ in mass from from each other and this is due to the different no. of electrons in their nucleus.
They have the same formulas but different organic structures.
An element is defined by the number of protons, so this cannot vary. Isotopes of a particular element are different in the number of neutrons within the atoms. These isotopes are said to be comparatively "lighter" or "heavier" than other isotopes based on the total of protons and neutrons (atomic mass).
Isotopes of an element have the same number of protons but different numbers of neutrons in their nuclei. This results in different atomic masses for each isotope. Despite the difference in atomic mass, isotopes of an element have similar chemical properties due to their identical electron configurations.
Radioisotopes are "radioactive isotopes"; they are not stable. Radioactive atoms will decay, or break apart into other atoms, by emitting an electron, or a neutron or a positron or an alpha particle (2 protons and two neutrons). The rate at which this happens is measured by the "half-life"; after one half-life, half of the atoms will have decayed. After another half-life, half of the remaining atoms will have decayed. Atoms with short half-lives are highly radioactive, and can be fairly dangerous. Atoms with long half-lives are only slightly radioactive, and aren't all that dangerous.
Neutral atoms of the same element can differ in the number of neutrons, which results in different isotopes of the same element. Isotopes have the same number of protons and electrons, but different numbers of neutrons.
Primarily, isotopes differ in the number of neutrons in the nucleus. Secondarily, because some combinations of protons and neutrons produce an unstable nucleus, they may differ by being radioactive.
A natural chemical element may be monoisotopic or has isotopes. Isotopes are atoms but they differ from other isotopes by the number of neutrons. This involve a different atomic mass and different physical properties or sometimes (for light isotopes) different chemical properties. Also, all chemical elements have radioactive, artificial isotopes.
They differ in their number of neutrons.Atoms of all isotopes of carbon contain 6 protons and 6 electrons.Carbon-12 is the most common isotope.Isotopes of an element differ because each isotope has a different neutrons, but the same amount of protons.Example: H-1H-2H-1 has 1 neutron, 1 proton, and 1 electronH-2 ,however, has 2 neutrons, 1 proton, and 1 electron.
Yes - by the basic definition of an element; excepting only isotopes of an element, which differ slightly from each other in atomic structure, but not enough to affect the element's outwards physical and chemical properties.
Isotopes of the same element differ in the number of neutrons. Isotopes of different elements differ in the number of protons and neutrons. For instance, carbon-12, a stable form of carbon, has 6 protons and 6 neutrons. Carbon-14, a radioactive form of carbon that occurs in nature, has 6 protons and 8 neutrons. Nitrogen-16, on the other hand, also radioactive and occurring in the primary coolant of nuclear power plants, has 7 protons and 9 neutrons.
