Chapter 8 - Abby Cataldo
Chemical formula - H2O
Structural formula - H-O-H
vocab
Diatomic Molecule - has 2 atoms
Polyatomic Ions - More than 2 elements to form molecule w/ charge
Polar Bonds - An unequal sharing of electrons
Octet rule - has to have 8 electrons
9 shapes of VSPER theory
linear triatomic
trigonal planar
bent triatomic
pyramided
tetrahedral
trigonal bipyramidal
octahedral
square planar
T-shaped
Molecular bonds
low boiling/melting point
gas/liquid at room temp.
Ionic bonds
high melting/boiling point
solid at room temp.
Ex:
H2O -> H-O-H
A - central element (O)
B - secondary element (H)
E - electron pairs
