What is the most important factor determining the geometry of a molecule or an ion?
The geometry of the molecule actually determines number of electron pairs on the central atom. The electron pairs will be arranged in such a way to minimize the repulsion and therefore, have the lowest possible energy.
What determines the molecular geometry of a molecule?
Consider: Number of bonding domains on the central atom Number of non-bonding electron pairs (lone pairs) on the central atom
What is the molecular shape of a molecule that has two electron pairs in which both pairs are shared?
linear
What is the geometry of molecule having one lone and three bond pairs?
Trigonal pyramidal
What is the molecular geometry of a methane (CH4) molecule?
Methane has a tetrahedral molecular geometry. It has 4 bonding pairs of electrons and no lone pairs.

What does the VSPER theory predict?
VSEPR theory predicts the geometrical arrangement of atoms in a molecule based on minimizing repulsion between electron pairs. It helps in determining the shape of molecules by considering the number of electron pairs surrounding a central atom.

How many lone and bond pairs are present in the S8 molecule?
two
How is VSEPR theory helpful?
VSEPR theory helps predict the molecular shape of a molecule based on the arrangement of its atoms and lone pairs. This information is useful for understanding the properties and reactivity of molecules, as well as for predicting their behavior in chemical reactions. Additionally, VSEPR theory can aid in determining the polarity of a molecule, which is important in explaining its interactions with other molecules.
How many lone pairs of electrons are there in a molecule of SO2?
There are two lone pairs of electrons in a molecule of SO2.
How many tatal lone pairs are present in molecule of KrF2?
There are three lone pairs present in a molecule of KrF2.
How many pairs of unbonded electrons does the water molecule have?
The water molecule has two pairs of unbonded electrons, also known as lone pairs. These lone pairs are located on the oxygen atom.
How many unshardd pairs of electrons are in a molecule of hydrogen iodide?
There would be three unshared pairs of electrons in a molecule of hydrogen iodide.
What base always base pairs with guanine?
In a DNA molecule cytosine always pairs with guanine, the same is true for an RNA molecule.
How does electron repulsion determine molecule shape?
Because they push the bonding pairs down. For example in a water molecule, it has 2 lone pairs which push the 2 bonding pairs down to form a V-shaped molecule. Hope this helps
