100

1. write the elements with their prefixes

2. the last element gets -ide

How do you name MOLECULAR compounds?

100

Atoms like to have 8 valence electrons around them. 

what is the octet rule?

100

Bookkeeping system to keep track of electrons within a lewis structure. 

The sum of all of this is zero. 

The smaller this is, the better. 

What is formal charge?

100

1 sigma and 2 pi bonds

triple bond

100

the measure of electrons in bonding and anti-bonding orbitals. 

what is a bond order?
200

 name of cation (charge) + base anion -ide

how do you name IONIC compounds?

200

These are the exceptions to the octet rule

Anything below the third row (expanded octets), radicals (odd number of electrons), B (wants 6), and H (wants 2). 

200

bond forms from overlap of half-filled orbitals between 2 atoms

What is Valence bond theory?

200

has unpaired electrons, interacts with a magnetic field (magnetic)

what is paramagnetic? 

200

This is the orbital with lower energy on a MO diagram. 

What is a bonding orbital?

300

the same lewis structures with a different position for delocalized electrons. 

What is resonance? 

300
∆EN =0-0.4


what is a nonpolar covalent bond? 

300

Valence Shell Electron Pair Repulsion

(this uses lewis structures to predict the geometry of the molecule)

what is VESPR theory?

300

Has no unpaired electrons, not magnetic. 

what does it mean to be diamagnetic?

300

Represented by a star in a MO diagram, this is the molecular orbital with higher energy

What is anti-bonding?

400

PbCl4

what is lead (IV) chloride?

400

∆EN= 0.5 -1.9



what is a polar covalent bond?

400

Bonds form when atomic orbitals combine to form molecular orbitals. 

what is Molecular orbital theory?

400

atomic orbitals can mix together to yield hybrid orbitals. 

What is orbital hybridization? 

400

Name this: SrI

what is strontium iodide?

500

magnesium bromide

MgBr2

500

∆EN = 2 or more

what is an ionic bond?

500

1-Bond where overlapping orbitals are pointed along the internuclear axis. 

2- overlapping orbitals are peperndicular to internuclear axis

What is the difference between a sigma bond (σ) and a Pi bond?

500

What is the hybridization of Br in BrF3?

HINT: draw the lweis structure, determine the electron geometry, and then find the corresponding hybridization orbital. 

sp3d

5 electron groups = trigonal bipyramidal= sp3d
