Isotopes are variants of a chemical element that have the same number of protons (atomic number) but different numbers of neutrons, resulting in different mass numbers. This means that while they belong to the same element, their atomic masses differ. Step 2: Example of IsotopesA common ...
Nuclei with certain number of nucleons are called as magic numbers are stable against nuclear decay. The principal factor that determine whether a nucleus is the neutron to proton ratio. Elements with atomic number more than 20 are lighter and these element's nuclei and have a ration of1...
Take carbon, for example. The ordinary carbon we find in the world around us is sometimes called carbon-12. It has six protons, six electrons, and six neutrons, so its atomic number is 6 and its relative atomic mass is 12. But there's also another form of carbon called carbon-14, ...
They have the same number of protons and electrons, but are different in the number of neutrons. As an example, consider the three isotopes of Candium. M&Ms, Skittles, and Reese's Pieces. They are all types of Candium with only one proton in the nucleus and one electron in an energy...
Two or more atoms having the same atomic number but the different mass numbers can be known as isotopes. The atomic number denotes the number of protons inside the nucleus of an atom. The number of protons remains the same for all isotopes....
Quantum theory is the branch of physics that deals with the world of atoms and the smaller (subatomic) particles inside them. You might think atoms behave the same way as everything else in the world, in their own tiny little way—but that's not true: on the atomic scale, the rules ...
With exotic matter, the only known baryonic matter becomes a minority. In a normal logical sequence, exotic matter should be a minority. Given the situation, baryonic matter should then be the missing mass or the theory should be called into question, that’s the way proposed for example by...
the first row only has electrons in the s orbital and none in p, d or f orbitals, and that gaps between hydrogen and helium, for example, could not possibly be filled because there isn’t anything to fill them with. similarly for the 2nd and 3rd row "gaps". this impossibility really...
“In order to unify gravitational force with the other three forces of nature we have to understand gravity as quantum theory. This means we need a theory in which the particle graviton is included in the atomic nucleus.” Researchers are now looking for signs of both supersymmetry and the To...
and then — oops — there'd be an atomic number for which there was no known element.And the uh prediction was that an element with that atomic number existed somewhere, but it just hadn't been found yet.And its location in the table would tell you what properties it should have.It ...
