The textbook example of a molecule with square planar geometry involves four fluorines bound to an element in this group.
The heaviest element in this group was synthesized by bombarding californium with calcium. The textbook example of a molecule with square planar geometry involves four fluorines bound to an element in this group. Ununoctium is technically a member of this group, which contains an element that potassium decays into, making it a viable alternative to carbon-14 dating. The most common element in this group is found in 0.94% of the atmosphere. For 10 points, identify this group with a full octet that contains xenon, radon, helium, and argon.
