Chapter 2:Covalent substances Flashcards
2A: Covalent Bonding
Pair of valence electrons that is shared between atoms in a covalent bond
Bond Pair
2A: Covalent Bonding
Bonding resulting from the sharing of electrons between non-metal atoms
Covalent Bonding
2A: Covalent Bonding
Covalently bonded pair of atoms of the same or a different non-metal element
Diatomic molecule
2A: Covalent Bonding
Attraction between opposite charges
Electrostatic attraction
2A: Covalent Bonding
Bonding between atoms within a molecule
Intramolecular molecules
2A: Covalent Bonding
Representation of a molecule where valence electrons are shown as dots
Lewis Structure
2A: Covalent Bonding
Electron pairs of valence electrons not shared with another atom in a covalent bond
Lone Pair
When two or more non-metal atoms are covalently bonded together
Molecule
Actual number of atoms in a molecule
Molecular formula
Covalent bond between two atoms of similar electronegativity
Non=Polar covalent bond
Permanent area of partial positive or partial negative charge on a molecule
Permanent dipole
Covalent bond between atoms of differing electronegativities
Polar covalent bond
Asymmetrical molecule with a partially positively charged end and a partially negatively charged end
Polar Molecule
Property of having a partial positive and negative charge
Polarity
Shows all the atoms and bonds in a molecule or compound
Structural Formula
Electron in an orbital by itself
Unpaired electron
Model used to predict the different shapes of molecules based on the repulsion between electron pairs
Valence shell electron pair repulsion theory (VSEPR)
