A Group 6 element is one in the series of elements in group 6 (IUPAC style) in the periodic table, which consists of the transition metals chromium (Cr), molybdenum (Mo), tungsten (W), and seaborgium (Sg). The period 8 elements of group 6 are likely to be either unpenthexium (Uph) or unpentoctium (Upo)(if possible, since drip instabilities may imply that the periodic table ends at unbihexium). Neither of them have been synthesized, and it is unlikely that this will happen in the near future.
Like other groups, the members of this family show patterns in its electron configuration, especially the outermost shells resulting in trends in chemical behavior:
| Z | Element | No. of electrons/shell |
|---|---|---|
| 24 | chromium | 2, 8, 13, 1 |
| 42 | molybdenum | 2, 8, 18, 13, 1 |
| 74 | tungsten | 2, 8, 18, 32, 12, 2 |
| 106 | seaborgium | 2, 8, 18, 32, 32, 12, 2 |
"Group 6" is the new IUPAC name for this group; the old style name was "group VIA" in the old European system or "group VIB" in the old US system. Group 6 must not be confused with the group with the old-style group names of either VIB (European system) or VIA (US system); that group is now called group 16.

Famous quotes containing the words group and/or element:
“It’s important to remember that feminism is no longer a group of organizations or leaders. It’s the expectations that parents have for their daughters, and their sons, too. It’s the way we talk about and treat one another. It’s who makes the money and who makes the compromises and who makes the dinner. It’s a state of mind. It’s the way we live now.”
—Anna Quindlen (20th century)
“What was any art but an effort to make a sheath, a mould in which to imprison for a moment the shining, elusive element which is life itself—life hurrying past us and running away, too strong to stop, too sweet to lose?”
—Willa Cather (1873–1947)
