Isobars are atoms 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 is 40 S, 40 Cl, 40 Ar, 40 K, and 40 Ca. While the nuclei of these nuclides all contain 40 nucleons, they contain varying ...
Examples include carbon-14, nitrogen-15, and oxygen-16 in the table above. Isobars are nuclides with the same number of nucleons (i.e. mass number) but different numbers of protons and neutrons. Isobars neighbor each other diagonally from lower-left to upper-right. Examples include carbon-14, nitrogen-14, and oxygen-14 in the table above.
An isobar (from Ancient Greek βάρος (baros) 'weight') is a line of equal or constant pressure on a graph, plot, or map; an isopleth or contour line of pressure. More accurately, isobars are lines drawn on a map joining places of equal average atmospheric pressure reduced to sea level for a specified period of time.
This list of nuclides shows observed nuclides that either are stable or, if radioactive, have half-lives longer than one hour. This represents isotopes of the first 105 elements, except for elements 87 ( francium ), 102 ( nobelium ) and 104 ( rutherfordium ).
Beta-decay stable isobars are the set of nuclides which cannot undergo beta decay, that is, the transformation of a neutron to a proton or a proton to a neutron within the nucleus. A subset of these nuclides are also stable with regards to double beta decay or theoretically higher simultaneous beta decay, as they have the lowest energy of all ...
A line of constant value on a map or chart. Examples include isobar (equal barometric pressure), isotherm (equal temperature), and isohyet (equal precipitation). Isoline (opera) , an opera by André Messager
Isobar may refer to: Isobar (meteorology), a line connecting points of equal atmospheric pressure reduced to sea level on the maps. Isobaric process, a process taking place at constant pressure; Isobar (nuclide), one of multiple nuclides with the same mass but with different numbers of protons (or, equivalently, different numbers of neutrons).
In physics, mirror nuclei are a pair of isobars of two different elements where the number of protons of isobar one (Z 1) equals the number of neutrons of isobar two (N 2) and the number of protons of isotope two (Z 2) equals the number of neutrons in isotope one (N 1); in short: Z 1 = N 2 and Z 2 = N 1.
