OCTET RULE
|
ATOMS TEND TO GAIN, LOSE, OR SHARE ELECTRONS UNTIL THEY HAVE A NOBLE GAS ELECTRON CONFIGURATION
(8 VALENCE ELECTRONS) |
|
|
IONIC BOND
|
THE ATTRACTION BETWEEN CATIONS AND ANIONS. METALS AND NONMETALS
FORMS BETWEEN ATOMS OF VERY DIFFERENT E.N. |
|
|
DUET RULE
|
H, LI, BE, B
PREFERS TO HAVE TWO ELECTRONS |
|
|
IONIC FORMATION FOR METALS
|
11Na- 1s2 2s2 2p6 3s1
Na+ 1s2 2s2 2p6 12 Mg- 1s2 2s2 2p6 3s2 Mg+2 - 1s2 2s2 2p6 metals lose electrons to form stable cations. |
|
|
IONIC FORMATION FOR NONMETALS
|
17Cl- 1s2 2s2 2p6 3s2 3p5
Cl- 1s2 2s2 2p6 3s2 3p6 Anions gain electrons to form stable anions. |
|
|
AN IONIC BOND FORMS WHEN AN ATOM THAT LOSES ELECTRONS BONDS WITH AN ATOM THAT
|
GAINS ELECTRONS
|
|
|
ELECTRONEGATIVITY
|
LEFT TO RIGHT IT INCREASES AND INCREASES AS YOU GO UP
HYDROGEN HAS ELECTRONEGATIVITY CLOSER TO THAT OF B AND CARBON |
|
|
COVALENT BOND
|
A BOND FORMED BY SHARING ELECTRONS. THE DIFFERENCE IN ELECTRONEGATIVITY BETWEEN ATOMS MUST BE SMALL.
NONMETALS BONDED TO NONMETALS. H BONDED TO NONMETALS |
