three groups bound to it with no lone pairs
Sulfur dioxide is an example of a molecule that has a tetrahedral arrangement of electron pairs due to its VSEPR geometry, but it is not a tetrahedral molecule. This is because it has a bent molecular shape, with two bonding pairs and one lone pair of electrons around the central sulfur atom.

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.
Three groups bound to it with no lone pairs
A molecule with a trigonal planar geometry around a central atom typically results from having three bonding pairs of electrons around the central atom, forming a flat triangle. This is commonly seen in molecules with sp2 hybridization, such as those with three sigma bonds and no lone pairs around the central atom.

The VSEPR theory explains how the geometric arrangement of atoms around a central atom in a molecule affects the molecule's shape. It helps predict the shape of molecules based on the number of electron pairs (both bonding and non-bonding) around the central atom.
Electrons influence the shape of a molecule through their distribution around the nucleus, which affects the bonding between atoms. The sharing or transfer of electrons between atoms makes chemical bonds that determine the geometry of the molecule. The arrangement of electron pairs (bonding and non-bonding) around the central atom determines the molecule's shape according to VSEPR theory.
The bond angle in a molecule can be determined by using the VSEPR theory, which predicts the shape of a molecule based on the number of electron pairs around the central atom. By knowing the number of bonding and non-bonding electron pairs, one can determine the bond angle in the molecule.
One method to determine the hybridization of the central atom in a molecule is to count the number of regions of electron density around the central atom. This can help identify the type of hybrid orbitals involved in bonding.
Ammonia (NH3) has a trigonal pyramidal shape due to its three bonding pairs and one lone pair of electrons around the central nitrogen atom.
One can predict molecular geometry by considering the number of bonding and non-bonding electron pairs around the central atom, using VSEPR theory. The arrangement of these electron pairs determines the shape of the molecule.
Sulfur dioxide is an example of a molecule that has a tetrahedral arrangement of electron pairs due to its VSEPR geometry, but it is not a tetrahedral molecule. This is because it has a bent molecular shape, with two bonding pairs and one lone pair of electrons around the central sulfur atom.
The bond angle of a tetrahedral molecule is approximately 109.5 degrees. This angle is due to the arrangement of four bonding pairs of electrons around the central atom, which causes the bonds to spread out as far apart as possible to minimize repulsion.
