  3. Group (periodic table) - Wikipedia

    en.wikipedia.org/wiki/Group_(periodic_table)

    Modern group names are numbers 1–18, with the 14 f-block columns remaining unnumbered (together making the 32 columns in the periodic table). Also, trivial names (like halogens) are common. In history, several sets of group names have been used, based on Roman numberings I–VIII, and "A" and "B" suffixes. [2] [3

    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.

    b Group 18, the noble gases, were not discovered at the time of Mendeleev's original table. Later (1902), Mendeleev accepted the evidence for their existence, and they could be placed in a new "group 0", consistently and without breaking the periodic table principle. r Group name as recommended by IUPAC.

    Boron (1s 2 2s 2 2p 1) puts its new electron in a 2p orbital; carbon (1s 2 2s 2 2p 2) fills a second 2p orbital; and with nitrogen (1s 2 2s 2 2p 3) all three 2p orbitals become singly occupied. This is consistent with Hund's rule , which states that atoms usually prefer to singly occupy each orbital of the same type before filling them with the ...
