Chemical Bonds
A mutual electrical attraction between the nuclei and valence electrons of different atoms that binds atoms together
What is chemical bond?
Number of valence electrons that can fill an outer shell
What is eight electrons?
Polar-covalent bonds form when their EN difference is between these two numbers
What is 0.3-1.7?
VSEPR theory predicts this
What is the three dimensional shape of molecules?
Sharing of electrons between two non-metals
What is covalent bond?
Transfer of electrons between metals and non-meals
What is ionic bond?
Name of the rule that states that eight valence electrons exist in the outer shell
What is the octet rule?
Non-polar covalent bonds form with an EN difference of this number
What is 0?
VSEPR theory can determine this in a bond
What is the angle of the bond?
An uneven distribution of charge
What is polar bond?
Electrons and protons share this force
What is attractive force?
Represent molecules and their shared and unshared electrons
What are Lewis structures?
Electrons are shared equally in this bond
What is polar-covalent bond?
VSEPR acronym stands for these words
What is valence shell electron pair repulsion?
Neutral group of atoms held together by covalent bonds
What is molecule?
This allows electrons to be shared
What is orbital shift?
This illustrates only the valence electrons, indicated by dots
What is electron-dot notation?
This is minimized when attractive forces are balanced by repulsive forces
What is potential energy?
This geometry has a distance of 120 degrees and contains three bonding pairs
What is trigonal planar geometry?
Three pairs of electrons shared between two atoms
What is triple bond or triple covalent?
Understood the ability of an atom in a molecule to attract shared electrons to itself
Who is Linus Pauling?
They cannot give away electrons to other atoms due to their high electron affinities
What are non-metals?
The seven diatomic molecules
What are Br, I, N, Cl, H, O, F?
What are unpaired electrons?
Occurs when more than one valid Lewis structure can be written for a particular molecule
What is a resonance structure?
