When the central atom of a molecule has unshared electrons the bond angles will?
When the central atom of a molecule has unshared electrons, the bond angles will be less than the ideal angles for a given molecular geometry. This is because the unshared electrons create additional repulsion, pushing the bonded atoms closer together and reducing the bond angles.
A molecule with a bent shape with a bond angle of 104.5 would have how many unshared electrons around the central atom Count electrons not electron pairs?
A molecule with a bent shape and a bond angle of 104.5 degrees typically has two unshared electrons around the central atom. This is because the oxygen atom (common in bent molecules) usually has 6 valence electrons with two shared and two unshared pairs.
Is ammonia molecule a tetrahedral?
The bond angles between two N-H bonds in ammonia are close to the bond angles characteristic of a tetrahedron, but the molecule as a whole is not a tetrahedron because one of the four bonds to a central atom found in an actual tetrahedral molecule is missing; there are only three hydrogen atoms bound to a central nitrogen atom in ammonia. In an ammonium ion, however, the tetrahedron is complete.
Which shape has a central atom with one unshared pair of electrons?
A molecule with a central atom having one unshared pair of electrons would have a linear shape. The unshared pair of electrons occupies more space and pushes the bonding pairs closer together, resulting in a linear geometry.
What is the difference between a molecule with a tetrahedral geometry and one with a trigonal pyramidal geometry?
A molecule with a tetrahedral geometry has four atoms bonded to a central atom in a symmetrical arrangement, while a molecule with a trigonal pyramidal geometry has three atoms bonded to a central atom in a triangular shape with one lone pair of electrons.

Which molecule has a tetrahedral arrangement of electron pairs but is not a tetrahedral 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.
Is ammonia molecule a tetrahedral?

What causes water molecules to have a bent shape according to VSEPR threory?
Repulsion of the unshared electron pairs (2)and the bonded pairs (2) around the central oxygen atom. Repulsion of these 4 electron pairs attempts to form a tetrahedral shape. Describing the molecular shape, we ignore the unshared electrons and just describe the shape of the molecule based on the location of the atoms, thus bent.
What is the difference between a molecule with a tetrahedral geometry and one with a trigonal pyramidal geometry?
A molecule with a tetrahedral geometry has four atoms bonded to a central atom in a symmetrical arrangement, while a molecule with a trigonal pyramidal geometry has three atoms bonded to a central atom in a triangular shape with one lone pair of electrons.
Why is CF4 a tetrahedral geometry?
It is tetrahedral because there are four electrons bonded to the central atom.
A molecule that has a central atom surrounded by three single bond pairs and one unshared pair would have a shape.?
The shape would tend to be trigonal pyramidal. An example would be ammonia, NH3.
How many unshared electrons and bonding electrons exist around the central atom in ozone O3?
In ozone (O3), there are 2 unshared electrons and 2 bonding electrons around the central oxygen atom. Each of the terminal oxygen atoms contributes a single unshared electron, while the central oxygen atom shares a pair of electrons with each terminal oxygen atom to form the bonds.
What is the molecular shape of CCl4?
CCl4 shape is circular. This is determined by the Valence Shell Electron Pair Repulsion theory (VSEPR). The repulsion of the molecule determines the shape of it. CCl4 has a tetrahedral shape, owing to four bond pairs of electrons repelling each other to positions of maximum separation and minimum repulsion. The angle between bonds is 109.5 degrees.
The shape of the methane molecule is called?
The shape of the methane molecule is called tetrahedral. It has a central carbon atom with four hydrogen atoms attached, forming a symmetrical tetrahedral shape with bond angles of approximately 109.5 degrees.
