2 electron groups are in CO2.
Proof, I got it wrong on a quiz. :(
trigonal pyramidal
Four electron groups - two bonded pairs and two lone pairs
group 13 or IIIA
minimizes the repulsion of electron groups
The vertical columns on a periodic table are called families, or groups. They share many characteristics, including atomic radii and how electron shells are filled.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
linear
Electron geometry for this is tetrahedral. There are two O-F single bonds, which makes 2 electron groups. There are two lone pairs around oxygen, which make up the last two electron groups. Molecules with four electron groups has a tetrahedral Electron geometry.

10 because there are 20 Valence Electrons that are pairing up.
Cobalt electron configuration is [Ar]3d7.4s2.Cobalt(2+) electron configuration is [Ar]3d7.
tetrahederal
trigonal pyramidal
3 electron groups classified as trigonal planar. The molecular geometry is Angular or Bent whichever you prefer to call the shape. The ideal bond angles are 120 degrees and the molecule is polar.
