Main Bonds
An attraction between atoms which creates substances with 2+ atoms.
What is a chemical bond?
Only requires 6 valence electrons.
What is boron?
Predicts the geometry of individual molecules from the number of electron pairs surrounding their central atoms.
What is the VSEPR theory?
Forces of attraction or repulsion between molecules.
What are intramolecular forces?
the intermolecular attractions resulting from the constant motion of electrons and the creation of instantaneous dipoles
This bond shares electrons equally between atoms.
What is a non-polar covalent bond?
Only require 2 valence electrons each.
What are hydrogen and helium?
Has 2 bonded pairs and 0 unbonded pairs
What is linear shape?
Multiple delocalized electrons being shared among positive ions in a lattice structure
Strongest force strength
What is metallic bonding?
This bond shares electrons unequally between atoms.
What is a polar covalent bond?
Electrons in the highest energy level of an atom.
What are valence electrons?
3 bonded pairs and one unbonded pair
What is trigonal pyramidal shape?
The transfer of electrons creates positive and negative ions.
What is ionic bond/force?
Weakest force strength
What is london-dispersion forces?
Electrons are transferred from one atom to another.
What is an ionic bond?
These show how valence electrons are arranged among atoms in a molecule.
What are Lewis Structures?
4 bonded pairs and 0 unbonded pairs
What is tetrahedral shape?
The electrostatic attraction between polar molecules of hydrogen bound to a highly electronegative atom and some other highly electronegative atom near it.
What is hydrogen bonding?
These types of forces have the highest boiling points.
This number determines the type of bond between atoms.
What is the electronegativity difference?
States that atoms prefer to have eight valence electrons in their valence shells.
What is the Octet Rule?
Both 2 bonded pairs and 1 unbonded pair and 2 bonded pairs and 2 unbonded pairs
What is bent shape?
the forces of attraction between polar molecules
What is a dipole-dipole force?
These types of forces have the lowest boiling points.
What are london dispersion forces?
