Lewis Structures
That most atoms like to have only 8 electrons on the outer shell.
What is the Octet rule?
The attractive and repulsive forces that arise between the molecules of a substance.
What are intermolecular forces?
A nonmetal atom shares its valence electrons with another nonmetal atom.
What is Ionic Bonding?
This molecular geometry, with a bond angle of 180°, occurs in molecules like CO2, where the central atom is bonded to two atoms.
What is Linear?
What is a pair of electrons that are shared between two atoms to form a covalent bond?
What is a Bond Pair?
The bond with 4 bonding electrons.
What is a double bond?
The force of attraction between polar molecules, equal but opposite charges.
What is the Dipole-Dipole Force?
The electrostatic attraction between positively charged metal “ions” and delocalized electrons.
What is Metallic Bonding?
In this molecular geometry, the central atom is surrounded by three bonds and no lone pairs, resulting in a bond angle of 120°.
What is Trigonal Planar?
What are a pair of electrons that are located on an atom but are not involved in bonding with another atom?
What is a Lone Pair?
The bond with 6 electrons.
What is a triple bond?
Methane and Iodine are compound examples of this intermolecular bond type.
What is the London Dispersion Force?
A weaker type of bonding that's a type of polar covalent bonding.
What is Hydrogen Bonding?
This molecular geometry occurs in water (H2O), where the central atom has two bonding pairs and two lone pairs, resulting in a bent shape.
What is Bent?
These pairs of electrons around a central atom can cause the geometry of a molecule to deviate from the ideal shape, especially when they are non-bonding.
What is the effect of lone pairs on molecular geometry?
This element often violates the octet rule in its Lewis structure by being stable with fewer than 8 electrons, as seen in BF3.
What is Boron?
The most powerful intermolecular force present in CO2.
What is the London Dispersion Force?
When there is an unequal sharing of electrons.
What is Polar?
his molecular geometry occurs in a molecule like SF6, where the central atom is surrounded by six bonding pairs, forming a 90° bond angle.
What is Octahedral?
In a molecule like methane (CH4), this type of pair of electrons is responsible for forming bonds between carbon and hydrogen atoms.
What is a bonding electron pair?
This is the total number of valence electrons in the Lewis structure of NaCl?
What is 8?
This bond causes NaCl to have a boiling point of 1413 Celsius.
What is Ionic Bonding?
This type of bond is formed when electrons are shared equally between two atoms with similar electronegativities, as seen in molecules like O2.
What is Non-polar Covalent?
This molecular geometry, with a bond angle of approximately 109.5°, is seen in molecules like methane (CH4), where the central atom is bonded to four atoms with no lone pairs.
What is Tetrahedral?
When these electron pairs are present in a molecule, they create regions of electron density that can push other electron pairs away, influencing bond angles and molecular shape.
What is electron pair repulsion?
