question
Periodic Table of elements
Periodic Table of elements
answer
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
question
Table S
Table S
answer
Electronegativity= tendency to attract electrons; higher the number, greater the reactivity
question
Table C
Table C
answer
Moving to that prefix- change the sign of the exponent Moving from- leave prefix
question
Table B
Table B
answer
Heat of fusion= melting point Vaporization= when it changes from liquid to gas
question
Table G
Table G
answer
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
question
Table F
Table F
answer
Used to predict the solubilities of compounds during a double replacement reaction Whatever is insoluble is the precipitate
question
Table H
Table H
answer
Dotted line= boiling point
question
Table I
Table I
answer
Negative H= exothermic reaction Positive H= endothermic
question
Table J
Table J
answer
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 reactionโ€” no reaction will occur if below H
question

Table M
answer
Below first number= first color Above 2nd number= 2nd color
