118 chemical elements have been identified and named officially by IUPAC.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).
Wikipedia categories named after chemical elements (120 C) Pages in category "Chemical elements" The following 124 pages are in this category, out of 124 total.
The fourth shell contains one 4s orbital, three 4p orbitals, five 4d orbitals, and seven 4f orbitals, thus leading to a capacity of 2×1 + 2×3 + 2×5 + 2×7 = 32. [30] Higher shells contain more types of orbitals that continue the pattern, but such types of orbitals are not filled in the ground states of known elements. [ 45 ]
The Elements" is a 1959 song with lyrics by musical humorist, mathematician and lecturer Tom Lehrer, which recites the names of all the chemical elements known at the time of writing, up to number 102, nobelium. Lehrer arranged the music of the song from the tune of the "Major-General's Song" from The Pirates of Penzance by Gilbert and Sullivan ...

Newlands arranged all of the known elements, starting with hydrogen and ending with thorium (atomic weight 232), into eight groups of seven, which he likened to octaves of music. [ 6 ] [ 7 ] In Newlands' table, the elements were ordered by the atomic weights that were known at the time and were numbered sequentially to show their order.
