Neon is a chemical element; it has the symbol Ne and atomic number 10. It is the second noble gas in the periodic table. [14] Neon is a colorless, odorless, inert monatomic gas under standard conditions, with approximately two-thirds the density of air.
Like the periodic table, the list below organizes the elements by the number of protons in their atoms; it can also be organized by other properties, such as atomic weight, density, and electronegativity. For more detailed information about the origins of element names, see List of chemical element name etymologies.
Periodic table of the chemical elements showing the most or more commonly named sets of elements (in periodic tables), and a traditional dividing line between metals and nonmetals. The f-block actually fits between groups 2 and 3 ; it is usually shown at the foot of the table to save horizontal space.
[97] [103] 21 Ne and 22 Ne are produced in the earth's crust as a result of interactions between alpha and neutron particles with light elements; 18 O, 19 F and 24,25 Mg. [104] The neon ratios (20 Ne/ 22 Ne and 21 Ne/ 22 Ne) are systematically used to discern the heterogeneity in the Earth's mantle and volatile sources. Complimenting He isotope ...
For phosphorus (element 15) as an example, the concise form is [Ne] 3s 2 3p 3. Here [Ne] refers to the core electrons which are the same as for the element neon (Ne), the last noble gas before phosphorus in the periodic table. The valence electrons (here 3s 2 3p 3) are written explicitly for all atoms.
This is a list of chemical elements and their atomic properties, ordered by atomic number (Z).. Since valence electrons are not clearly defined for the d-block and f-block elements, there not being a clear point at which further ionisation becomes unprofitable, a purely formal definition as number of electrons in the outermost shell has been used.

Many other names have been used for this set, and its borders are not agreed on. Precious metals – Variously-defined group of non-radioactive metals of high economical value. Superactinides – Hypothetical series of elements 121 to 157, which includes a predicted "g-block" of the periodic table.
