Pairs of electrons localized on one atom
Pairs of electrons shared between atoms
As the number of bonds increase, bond energy ____
As the number of bonds decrease, bond length _____
Electrons are negatively charged and therefore repel each other. Distances between electron pairs are maximized
How is the number of bonding pairs determined?
How many elements are bonded to the central atom
Multiple bonds make a ____ distance
How are the number of lone pairs determined?
How many pairs of atoms are attached to the central atom
What is correlated to bond angle?
Total number of electron areas
How do you find the total electron area?
Bonding area + lone pairs
How do you determine electron pair geometry?
Total electron areas
How do you determine the molecular geometry?
Electrons are not shared equally in a covalent bond
Electrons are shared equally in a covalent bond
What is the trend of electronegativity on the periodic table?
Left to right increases, up and down decreases
When dipoles cancel out it is (polar or nonpolar)
When dipoles do not cancel out it is (polar or nonpolar)
If the molecule is symmetric it is usually (polar or non polar)
If the molecule is nonsymmetric, it is usually (polar or non polar)
