Poly Atomic Name

What is a Poly Atomic ion?
a charged particle consisting of two or more covalently bonded atoms. They remain together through most chemical reactions
Molecular vs ionic compound
– molecular compounds (covalent) share electrons, and form between two non-metals. Ionic give electrons and form between a metal and nonmetal
Polar vs nonpolar bonds
– different elements = usually polar, same element = nonpolar
Electronegativity
a measure of the attraction of an atom of that element in a molecule for a pair of shared electrons. Atoms on the right of periodic table are more electronegative than those on the left. Atoms at top of a column are generally more electronegative than the bottom.

avogadro’s number

parts of a solution
solute: item in lesser amount. Solvent: Item in greater amount (usually does the dissolving)
Molarity (M)
moles of solute/L of solution
Energy
ability to do work or cause change
Potential E
Energy of position (stored E)
Kinetic E
Energy of Motion
For Chemical reaction to occur:Bond breaking is ________.Bond Formation is ________.
breaking requires input of energy (endothermic)Bond formation releases energy (exothermic)
E of Activation
the amount of energy required for a reaction to occur
catalyst
lowers E of Activation
Entropy
degree of disorder
Energy of Fusion
increase in E input but temp stays the same
(specific) heat capactiy
amount of energy required to raise the temperature of a substance a given amount. i.e. solid to liquid
