21 mar 2023 · Chalcogens, commonly referred to as the Oxygen Group or Group 16, are a group of chemical elements on the periodic table that share distinctive properties because of their valence electron configuration.
First, let’s look at Periodic Table and Group numbering. 14.1 Hydrogen. The simplest atom, ~90% of all atoms in the universe. The only element whose isotopes are each given a different symbol and name. 1H (or H, protium) = one proton (p+), plus one e-surrounding it. 2H (or D, deuterium) = one p+ and one neutron (n), plus one e-
Oxygen is a chemical element with the symbol O and atomic number 8. It is a member of the chalcogen group in the periodic table, a highly reactive nonmetal, and a potent oxidizing agent that readily forms oxides with most elements as well as with other compounds.

Some of the groups have collective names: group one are the alkali metals; group two are the alkaline earth metals; group eleven are the coinage metals; group seventeen are the halogens; and group eighteen are the noble gases. The first widely recognised table was published in 1869 by the Russian chemist Dmitri Mendeleev. Br 35 Bromine 79.9040 ...
