2.5 Flashcards
Double Bond
Covalent bond in which two pairs of electrons are shared between two atoms
Hypervalent Molecule
Molecule containing at least one main group element that has more than eight electrons in its valence shell
Lewis Stucture
Diagram showing lone pairs and bonding pairs of electrons in a molecule or an ion
Lewis Symbol
Symbol for an element or monatomic ion that uses a dot to represent each valence electron in the element or ion
Lone Pair
Two valence electrons in a molecule or ion; structure that includes only the placement of the atoms in the molecule
Octet Rule
Guideline that states main group atoms will form structures in which eight valence electrons interact with each nucleus, counting bonding electrons as interacting with both atoms connected by the bond
Resonance Hybrid
Average of the resonance forms shown by the individual Lewis structures
Single Bond
Bond in which a single pair of electrons is shared between two atoms
Triple Bond
Bond in which three pairs of electrons are shared between two atoms
