Four. Ammonia (NH3) is an example.
Carbon has four Hydrogen atoms around it.It is in tetrahedral shape
Silicon Tetrafluoride has a tetrahedral molecular geometry. That means there are 4 F atoms around the central atom Si.
C2H4Cl2 (dichloroethane) has tetrahedral geometry around both carbon atoms. The geometry can be changed from free rotation to restricted rotation which has the formula of C2H2Cl2.
Trigonal pyramidal. As has 5 valence electrons. It forms single bonds with each of the F atoms, donating one electron to each bond. This leaves 2 unbonded electrons, or a single lone pair. Thus the molecule has 4 different groups attached to As, and the electron configuration is tetrahedral. A tetrahedral configuration with one lone pair results in a trigonal pyramidal molecular geometry.
CdCl4 2- has a tetrahedral molecular geometry. Two of the Cl atoms form normal single bonds with Cd and the other two share 2 of their electrons with the empty p-orbital on Cd.
It means that the 4 hydrogen atoms of a methane molecule are at the vertices of a regular tetrahedron with the carbon atom at its centre.
tetrahedral
C2H4Cl2 (dichloroethane) has tetrahedral geometry around both carbon atoms.
Tetrahedral with P atoms at the vertices (corners)
In a tetrahedral molecule the characteristic angle between atoms is 109,5 degrees.
Oxygen has 6 electrons in its outer shell but attains 8 when it bonds with the two hydrogen atoms in a water molecule. This makes 4 pairs of two. Theelectron geometry is therefore a tetrahedral (4 apices). Because the two hydrogens are attached to two of these apices they form a V shape.

109.5 degrees
Such a molecule is trigonal but due to presence of lone pair the bond angle is less than 120 degree as HNO2 the central atom is nitrogen. O=N..-OH
Silicon Tetrafluoride has a tetrahedral molecular geometry. That means there are 4 F atoms around the central atom Si.
C2H4Cl2 (dichloroethane) has tetrahedral geometry around both carbon atoms. The geometry can be changed from free rotation to restricted rotation which has the formula of C2H2Cl2.
The electron-group geometry of SeCl2 is tetrahedral. Its molecular geometry is bent. SeCl2 has one selenium atom and two chlorine atoms.
