Unlike with Groups 3, 4 where 'Crystallogens' and 'Icosagens' are alternative names that are not officially recognised by IUPAC, 'Chalcogens' is an IUPAC accepted name Main Group Elements - The elements in groups 1 and 2, as well as those numbered 13 to 18, are referred to as main group elements or representative elements. Groups may also be First-Element Uniqueness First elements of the main groups tend to show some unique chemistry not shown by the heavier elements of the group. Element Groups vs Element Families. • Gray The group number. 998; 10 Ne Neon 20. There are 18 element groups, which appear on the periodic table as numbers listed above the element columns. The temporary names are cumbersome, so it’s perfectly 8. As we move down in a group the number of valence electrons does not change. This 1868 table listed the elements in order of atomic weight, with elements with the same valency arranged in vertical lines, strikingly similar to Mendeleev’s table. 24. 01 → Atomic weight • Atomic number = number of protons found in the nucleus of an atom o Also indicates the number of electrons surrounding the nucleus of an atom.

Oxidation states of elements like O 2, S 8, H 2, P 4, Fe, etc are zero. Cosets and Lagrange’s Theorem 19 7. Describe what happens when two atoms of potassium react with one atom of sulfur. The heavy orange zigzag line running diagonally from the upper left to the lower right through groups 13–16 in Figure \(\PageIndex{1}\) divides the elements into metals (in blue, below and to the left of the line) and nonmetals (in bronze, above and to the right of the line).
