Geometry Concepts
If all the bonds in a molecule are double or triple bonds, that molecule must have this shape
Linear
CO2 is an example
Definition of an Ionic bond (include types of elements that do this)
Non-metals steal electrons from metals, creating oppositely charged ions that stick together.
Draw the lewis structure, including any partial charges, and determine the 3d shape.
Te2
Linear, non-polar double bond with 2 lps on each
An authors craft, ironically.

Wright
Atoms that can form bent molecules when central must have this many lone pairs, and this many unpaired electrons
2 lp
2 unpaired
Oxygen, sulfur are examples
Definition of a polar covalent bond (include types of elements that do this)
Non-metals share an electron unevenly, resulting in partial charges based on differences in electronegativity.
Draw the lewis structure, including any partial charges, and determine the 3d shape.
CAtF3
tetrahedral, all single bonds, At partial plus, Fs partial negative, polar molecule
Famous Michelangelo statue, currently resides in Florence.

Atoms that can form tetrahedral molecules when central must have this many lone pairs, and this many unpaired electrons
zero lp
4 unpaired
Carbon, silicon are examples
Definition of electronegativity.
Atoms ability to attract an electron
Draw the lewis structure, including any partial charges, and determine the 3d shape.
SbAtH2
trigonal pyramidal, Sb central with 1 lp, no partial charges, non-polar

Evan
My chompers, in broken french
Monteith
Atoms that can form trigonal pyramidal molecules when central must have this many lone pairs, and this many unpaired electrons
One lp
3 unpaired
Nitrogen, phosphorus are examples
Which would you expect to have a larger atomic radius Zr or Te, and why?
Zr, same row but farther to the left, has same number of shells but fewer protons, electrons are less attracted to nucleus (lower electronegativity).
Draw the lewis structure, including any partial charges, and determine the 3d shape.
SiS2
linear, 2 double bonds, S partial negative, Si partial plus, non-polar (symetrical)
Shares a name with a SSSAS teacher whose child went to college with Mr. Perez
Team devotee
one half of a standard switch
Fannon
For a molecule to have a trigonal planar shape, the molecules around the central atom must be arranged in this way... (think bonds, lone pairs, unpaired, etc)
Which would you expect to have a larger atomic radius Po or Se, and why?
Po, same column, lower down, more shells, valence electrons farther from nucleus and have more repulsive electron shells between them and protons, less access/lesser attraction to protons (lower EN)
Draw the lewis structure, including any partial charges, and determine the 3d shape.
SnPoH2
trigonal planar, Sn central Po double bonded, no partial charges.
