What is the atomic arrangement of a AX5E atom?
square pyramidal
What is the atomic arrangement of a AX4E2 atom?
Square Planar
What are the exceptions to the octet rule?
- Expanded Valence shells
- Elements in the period 3 and beyond can have 8+ shells around them (due to the presence of d orbitals) - Incomplete Octets
- Be, B, and Al may have less then 8 electrons - Odd-electron species
- an electron that doesn’t fit into a pair or a bond
Can you double bond fluorine?
NOPE
Formal Charge
The difference between the number of valence electron in three atom and the number of electrons assigned to it in the molecule
Valence Bond Theory
A covalent bond is formed when atomic orbitals overlap and a pair of electrons is located in the region between atoms
How many effective bonds are in a triple bond?
1
VESPR theory considers multiple bonds as only 1 effective pair
Resonance (atomic geometry)
The molecule can have more than one structure
