In the periodic table of the elements, each column is a group. In chemistry, a group (also known as a family) [1] is a column of elements in the periodic table of the chemical elements. There are 18 numbered groups in the periodic table; the 14 f-block columns, between groups 2 and 3, are not numbered.
In 1902, having accepted the evidence for the elements helium and argon, Dmitri Mendeleev included these noble gases as group 0 in his arrangement of the elements, which would later become the periodic table. [11] Ramsay continued his search for these gases using the method of fractional distillation to separate liquid air into several components.
Neon's polarisability of 0.395 Å 3 is the second lowest of any element (only helium's is more extreme). Low polarisability means there will be little tendency to link to other atoms. [1] Neon has a Lewis basicity or proton affinity of 2.06 eV. [2] Neon is theoretically less reactive than helium, making it the least reactive of all the elements ...
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 ...

Neon in an electrical discharge tube. Neon has a density of 9.002 × 10 −4 g/cm 3, liquifies at −245.95 °C, and solidifies at −248.45 °C. It has the narrowest liquid range of any element and, in liquid form, has over 40 times the refrigerating capacity of liquid helium and three times that of liquid hydrogen.
