The electron geometry is tetrahedral when there are 4 electron groups around the central atom. This means the electron groups are arranged in a 3D shape resembling a pyramid with a triangular base.
three dimensional arrangement of atoms electron-group geometry
If there are only three electron groups around an atom, they would be arranged in a trigonal planar geometry. This arrangement minimizes repulsion between the electron groups, placing them 120 degrees apart in a flat plane. The central atom would have a bond angle of approximately 120 degrees between the electron groups. If one of the groups is a lone pair, the geometry would adjust to a trigonal pyramidal shape.
In VSEPR theory, electron groups (bonding pairs and lone pairs) around a central atom arrange themselves in a way that minimizes repulsion, resulting in various molecular geometries such as linear, trigonal planar, tetrahedral, trigonal bipyramidal, and octahedral. The number of electron groups around the central atom determines the molecular geometry.
The molecular geometry around a central atom is the same as the electron group geometry when there are no lone pairs of electrons on the central atom. In such cases, all electron groups (bonding pairs) are arranged symmetrically around the atom, leading to identical geometries. This typically occurs in molecules with linear, trigonal planar, or tetrahedral arrangements, depending on the number of bonding pairs.
linear
The spatial arrangement of electron groups around the central atom is called molecular geometry. It describes the three-dimensional arrangement of atoms in a molecule.
2 electron groups are in CO2. Proof, I got it wrong on a quiz. :(

To determine the hybridization of an atom, you can look at the number of electron groups around the atom. The hybridization is determined by the number of electron groups, which can be bonding pairs or lone pairs. The most common types of hybridization are sp, sp2, and sp3, which correspond to one, two, and three electron groups, respectively. By counting the electron groups, you can determine the hybridization of the atom.
electron-group geometry
To determine the hybridization of an atom from its Lewis structure, count the number of electron groups around the atom. The hybridization is determined by the number of electron groups, with each group representing a bond or lone pair. The hybridization can be identified using the following guidelines: If there are 2 electron groups, the hybridization is sp. If there are 3 electron groups, the hybridization is sp2. If there are 4 electron groups, the hybridization is sp3. If there are 5 electron groups, the hybridization is sp3d. If there are 6 electron groups, the hybridization is sp3d2.

trigonal pyramidal
The answer is 1. This is because the only atom with lone paires is phosphorus and it only has 1.

The hybridization is based on the number of electron groups, which can be bonding pairs or lone pairs. The most common hybridizations are sp, sp2, and sp3, corresponding to 2, 3, and 4 electron groups, respectively.
