Groups of the Periodic Table
|
Alkali Metals - extremely reactive. Shiny, silver metals
Alkaline Earth Metals - fairly reactive Metalloids - has both metallic & non-metallic props. Halogens - most reactive non-metals Nobel Gases -all gases at room temp, very unreactive |
|
Ion Formation
|
Noble gases are stable as energy levels are full (stable octet), other atoms gain/lose to become stable
Metals tend to lose electrons (cations) Non-Metals tend to gain (anions) |
|
Ionic Compounds
|
-a binary compound contains 2 elements
-a binary ionic compoound forms when a metal loses one or more electrons to a non metal (transfer) -ions are held together by attraction |
|
Ionic Compounds containing Type ll Mulitvalent Metals
|
Still binary ionic metal (metal-cation, non metal-anion)
this time metal can form ion with more than one possible charge (multivalent) |
|
Tertiary Ionic Compounds
|
More than one atom, bonded together which carry a charge.
|
|
Molecular (Covalent) Compounds
|
Molecular Compound
compound formed due to the sharing of unpaird electrons (2 or more non-metals covalently bonded) Covalent Bond forms when a pair of electrons between to non metals are shared. Valence shells overlap and shared electrons are attracted to the nuclei of both atoms, bonding them together. Electrons are not transferred, atoms remain uncharged |

Classifying Chemical Reactions
|
Synthesis Reaction
A+B = AB Decomposition Reaction a ionic compund breaks down 2 or more products usually requires some sort of catalyst Single Displacement Reaction a reactive element (metal or non-metal) and a compound react, one element displaces another Double Displacement Reaction positive ions of 2 compounds change places and form two new compounds |
|
Neutralizing Reactants
|
Special case of double displacement involving acid and base
ACID+BASE---> IONIC SALT+WATER a 2nd form ACID+CARBONATE BASE--> AQUEOUS IONIC SalT+WATER+C0 |
