    the carbon group is a periodic table group consisting of carbon (c), silicon (si), germanium (ge), tin (sn), lead (pb), and flerovium (fl). it lies within the p-block.

    in modern iupac notation, it is called group 14. in the field of semiconductor physics, it is still universally called group iv. the group was once also known as the tetrels (from the greek word tetra, which means four), stemming from the roman numeral iv in the group names, or (not coincidentally) from the fact that these elements have four valence electrons (see below). they are also known as the crystallogens.
