Chemistry Reference Table Review

Number in upper right hand corner= charge Number in lower left hand conrner= atomic number/ number of protons Number in upper left hand corner= mass number #-#= electron shells; last one is the valence electrons Group- goes down; elements similar; increase reactivity (metals and nonmetal) Period- goes across; decrease reactivity Metals= groups 1-12 (excluding hydrogen); parts of 13 Nonmetals= groups 14-18 Transition metals= B, Si, Ge, As, Sb, Te, Po, At

Electronegativity= tendency to attract electrons; higher the number, greater the reactivity

Moving to that prefix- change the sign of the exponent Moving from- leave prefix

Heat of fusion= melting point Vaporization= when it changes from liquid to gas

On the curve= saturated Under the curve= unsaturated Above the curve= supersaturated Gases= downward slope Solids= upward curve If it asks how much will precipitate out- find point given, move down until touch the line, subtract, answer is new grams Higher you are, the more concentration

Used to predict the solubilities of compounds during a double replacement reaction Whatever is insoluble is the precipitate

Dotted line= boiling point

Negative H= exothermic reaction Positive H= endothermic

When dealing with acids and bases, if the metal an acid is reaction with is higher than H2, then the reaction will result in a single replacement reaction— no reaction will occur if below H

Below first number= first color Above 2nd number= 2nd color
