Totally Formal
The formula used to calculate the formal charge of an atom in a Lewis structure
What is Valence Electrons- dots- lines
Is this symbol placed between different valid resonance structures to show that the actual molecule is a hybrid of them?
What is an arrow
<->
This type of covalent bond is formed by the head to head overlap of atomic orbitals along the internuclear axis
What is a sigma bond
A central atom surrounded by four electron domains features this electron-domain geometry and hybridization
What is tetrahedral and SP3
This term describes electrons that are spread out over several atoms through overlapping p orbitals instead of being locked between two
Delocalized electrons
The most faverable structure based on formal charge has a charge of this
What is closest to zero
True or False, Resonance structures mean a molecule rapidly shifts between different forms
False, the molecule is a blend of two different structures and does not flip back and forth.
This type of covalent bond is formed by the side by side overlap of unhybridized P orbitals
What are Pi bonds
Three electron domains around a central atom give it SP2hybridization and this ideal bond angle
What is 120o
Trigonal Planar
This statement evaluates whether sigma bonds can freely rotate around their axis while pi bonds restrict rotation
What is ture?
In a standard neutral carbon monoxide (CO) molecule, what is the formal charge on the carbon atom?
-1
Compared to a pure single bond, resonance bonds possess this distinct combination of length and strength.
What are shorter and stronger
A single covalent bond consists of this many sigma bonds and this many pi bonds
One sigma and zero Pi bonds
Linear molecular geometry corresponds to a steric number of two, and this specific hybridization
What is sp hybridization
If a carbon atom participates in a double bond and two single bonds this exact number of unhybridized p orbitals remains on that carbon
What is one?
The sum of the formal charge of a polyatomic ion must equal the charge if the ion
True
In the Ozone molecule (O3) this decimal value represents the bond order of the oxygen-oxygen bonds
What is 1.5
A triple bond is made up of this exact breakdown of sigma and pi bonds
What is one sigma and two pi bonds
Expanded octet molecules, like PCl5, utilize this type of orbital mixing
What is sp3d2
Second-row elements cannot exceed an octet because they lack the electrons that third-row elements have readily available
What are low-energy d orbitals?
What is the formal charge of Sulfur in the sulfate ion (SO4-2)
+2
When drawing the resonance structure for (NO3-), this exact number of equivalent valid structures can be drawn
