VSEPR
If a molecule has 2 or more resonance structures, the ________ model can be applied to any one of them.
reactivity
The shape (geometry) of a molecule influences physical and chemical properties, including melting point, boiling point, and ________.
180°
________- not less than because theres no other way to minimize repulsion.
Valence electron pairs
________ repel each other.
Lone pair electrons
________ take up more space and therefore experience more repulsion.
Electrons
________ in bonds take up less space.
atomic size increases
When ________, lone pairs occupy larger spatial volumes, so angles between bonded atoms tend to be even smaller.
Valence Shell Electron Pair Repulsion (VSEPR) Theory based on Lewis structures and the principles that
Valence electron pairs repel each other
The geometry around the central atom will minimize the repulsion
180°
not less than because theres no other way to minimize repulsion
The shape (geometry) of a molecule influences
physical and chemical properties, including melting point, boiling point, and reactivity
VSEPR Nomenclature
A = central atom
X = bonding atom
E = lone pair
steric number
number of atoms bonded to central atom + number of lone pairs
