For other uses, see Neon (disambiguation). Chemical element with atomic number 10 (Ne) Neon, 10 Ne Neon Appearance colorless gas exhibiting an orange-red glow when placed in an electric field Standard ...
The darker more stable isotope region departs from the line of protons (Z) = neutrons (N), as the element number Z becomes larger. This is a list of chemical elements by the stability of their isotopes. Of the first 82 elements in the periodic table, 80 have isotopes considered to be stable. [1] Overall, there are 251 known stable isotopes in ...
A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [ 1 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...

The abundances of the naturally occurring isotopes of neon. Neon (10 Ne) possesses three stable isotopes: 20 Ne, 21 Ne, and 22 Ne. In addition, 17 radioactive isotopes have been discovered, ranging from 15 Ne to 34 Ne, all short-lived. The longest-lived is 24 Ne with a half-life of 3.38(2) min. All others are under a minute, most under a second.
The noble gases have also been referred to as inert gases, but this label is deprecated as many noble gas compounds are now known. [6] Rare gases is another term that was used, [7] but this is also inaccurate because argon forms a fairly considerable part (0.94% by volume, 1.3% by mass) of the Earth's atmosphere due to decay of radioactive ...
So, the nearby movements in the water cause protons to pass through their bodies, creating electrical pulses, which trigger chemical reactions. These reactions, in turn, activate a protein called ...
A nuclide is a species of an atom with a specific number of protons and neutrons in the nucleus, for example, carbon-13 with 6 protons and 7 neutrons. The nuclide concept (referring to individual nuclear species) emphasizes nuclear properties over chemical properties, whereas the isotope concept (grouping all atoms of each element) emphasizes chemical over nuclear.
