1
Turn in warm-ups for the last 2 weeks
List 3 things that you know about the periodic table
2
Periodic Table
3
Main Groups Metals-left side
Luster, conductors, malleable, ductile, solids Positive ions
4
Main Groups Nonmetals-far right side
Dull, insulators, shatter, brittle Negative ions
5
Main Groups Metalloids-middle intermediate characteristics
Elements touching black line (except Aluminum)
6
Hydrogen Nonmetal 1 valence electron Forms 1+ or rarely 1- ions
7
Alkali Metals 1 valence electron Forms 1+ ions
Found in compounds in nature Very reactive
8
Alkaline Earth Metals 2 valence electrons Forms 2+ ions
Found in compounds in nature Not as reactive as the Alkali Metals
9
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!
10
Boron Family 3 valence electrons Form 3+ ions
11
Carbon Family 4 valence electrons Forms 4+ ions
12
Nitrogen Family 5 valence electrons Forms 3- ions
13
Oxygen Family 6 valence electrons Form 2- ions
14
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!
15
Noble Gases 8 valence electrons Most are non-reactive All are gases
16
Inner Transition Metals
Lanthanide Series Actinide Series
17
Label the columns, charges and valence electrons, and metals, non-metals, metaloids
18
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
20
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
