Bonding Types Category Name
$100 Question: This type of bond involves the complete transfer of electrons from a metal to a nonmetal.
What is an ionic bond?
These valence electrons are represented as pairs of dots in a Lewis structure and are not involved in bonding.
What are lone pairs (or unshared pairs)?
This acronym stands for the theory used to predict molecular shapes based on the idea that electron pairs repel each other.
What is VSEPR theory?
These are the weakest of all intermolecular forces, existing between all molecules, including nonpolar ones.
London dispersion forces
This property measures an atom's ability to attract shared electrons in a chemical bond.
What is electronegativity
This type of bond occurs when two nonmetals share electrons equally.
What is a nonpolar covalent bond
This rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of eight valence electrons.
What is the octet rule?
A molecule with two bonding pairs and zero lone pairs around the central atom has this geometric shape.
a linear
This IMF occurs when the positive end of one polar molecule is attracted to the negative end of another polar molecule
dipole-dipole interaction
Because it has a symmetrical linear shape and its dipoles cancel out, Carbon Dioxideis classified as this type of molecule
What is a nonpolar molecule
In this type of covalent bond, electrons are shared unequally due to a difference in electronegativity.
What is a polar covalent bond?
This element is a notable exception to the octet rule, requiring only two electrons to achieve stability.
What is Hydrogen?
This is the molecular shape of a methane ($CH_4$) molecule, which has four bonding pairs and zero lone pairs.
What is tetrahedral
This exceptionally strong type of dipole-dipole force occurs when hydrogen is bonded to N, O, or F
What is a hydrogen bond
This type of bond is represented by drawing a single solid line between two atomic symbols in a Lewis structure.
single covalent bond
This type of bonding is characterized by a "sea of mobile electrons" surrounding positive metal ions.
What is metallic bonding?
This type of covalent bond is formed when two atoms share a total of four electrons (two pairs).
What is a double bond?
Due to the strong repulsion of its two lone pairs, a water molecule has this specific geometric shape.
What is bent
Of the three main IMFs, this is the primary force holding nonpolar $CO_2$ molecules together in dry ice.
What are London dispersion forces
This is the bond angle typically associated with a perfect tetrahedral molecular geometry.
What is 109.5 degrees
Predict the bond type between Sodium (Na) and Chlorine (Cl) based on their positions as a metal and a nonmetal.
What is an ionic bond?
This is the total number of valence electrons that must be drawn in the Lewis structure for a molecule of water
What is 8?
A central atom with three bonding pairs and one lone pair (like ammonia) results in this molecular geometry
What is trigonal pyramidal
Generally, molecules with stronger intermolecular forces will have this property elevated, requiring more energy to change from liquid to gas
higher boiling point
This specific physical property explains why water forms droplets and has a high "skin-like" resistance, caused by strong hydrogen bonding
skin tension
