forms when two or more atoms covalently bond and is lower in potential energy than its constituent atoms
a model that uses electron-dot structures to show how electrons are arranged in molecules
(pairs of dots or lines represent bonding pairs or electrons)
bond dissociation energy
the amount of energy required to break a specific covalent bond (always positive)
a single covalent bond that is formed when an electron pair is shared by the direct overlap of bonding orbitals
condition that occurs when more than one valid Lewis structure exists for the same molecule
Valence Shell Electron Pair Repulsion model, which is based on an arrangement that minimizes the repulsion of shared and unshared pairs of electrons around the central atom
geometry (shapes) of molecules
refers to the position of atoms; determined by the number of electron clouds
non-polar covalent bond
a type of bond that forms when electrons are shared equally between the two atoms
polar covalent bond
a type of bond that forms when electrons are not shared equally between the two atoms
inter-molecular forces (van der waals forces)
the attraction between individual molecules in a covalent bond (weak)
the attractive forces caused by dipole moments (separation of charge; opposite poles) between polar molecules
"strongest of the weak"
special dipole forces of attraction between hydrogen and very electronegative elements of F, O, and N only
ionic compound naming
1. name the cation first and the anion second
2. monatomic cations use the element name
3. monatomic ions take their name from the root of the element name plus the suffix -ide
4. to distinguish between multiple oxidation numbers of the same element, the name of the chemical formula must indicate the oxidation number of the cation. the oxidation number is written as a Roman numeral in parentheses after the name of the cation (Stock System).
5. if the compound contains a polyatomic ion, simply name the ion
6. in binary/tertiary compounds, write the formula in the smallest ratio possible (empirical formula)
