Turn in warm-ups for the last 2 weeks List 3 things that you know about the periodic table
Periodic Table
Main Groups Metals-left side Luster, conductors, malleable, ductile, solids Positive ions
Main Groups Nonmetals-far right side Dull, insulators, shatter, brittle Negative ions
Main Groups Metalloids-middle intermediate characteristics Elements touching black line (except Aluminum)
Hydrogen Nonmetal 1 valence electron Forms 1+ or rarely 1- ions
Alkali Metals 1 valence electron Forms 1+ ions Found in compounds in nature Very reactive
Alkaline Earth Metals 2 valence electrons Forms 2+ ions Found in compounds in nature Not as reactive as the Alkali Metals
Transition Metals Most common metals Can have multiple ion charges Relatively non-reactive Chemical reactions result in a color change Mercury (Hg) is a liquid at room temp STAR THIS ON YOUR PERIODIC TABLE!
Boron Family 3 valence electrons Form 3+ ions
Carbon Family 4 valence electrons Forms 4+ ions
Nitrogen Family 5 valence electrons Forms 3- ions
Oxygen Family 6 valence electrons Form 2- ions
Halogens 7 valence electrons Form 1- ions Found in compounds in nature Very reactive Bromine is a liquid at standard temp STAR THIS ON YOUR PERIODIC TABLE!
Noble Gases 8 valence electrons Most are non-reactive All are gases
Inner Transition Metals Lanthanide Series Actinide Series
Label the columns, charges and valence electrons, and metals, non-metals, metaloids
Label the following on your periodic table: Color and name the columns of the main group elements Number of valence electrons in that column Charge in that column Metals Non-metals Metalloids Transition metals Inner transition metals – label lanthanides and actinides
Periodicity Electronegativity- Ability to attract electrons in a chemical bond Atomic Radius- Size of neutral atoms Ionic Radius- Size of ions 1st ionization energy- Energy needed to pull off one electron Francium, Fr Large radius Low ionization energy Low electronegativity Fluorine, F Small radius High ionization energy High electronegativity
