Ionic & Covalent Bonds
Electronegativity
VSEPR shapes & Polarity
Intermolecular Bonding
Scale of Forces
100
The bond created by positive and negative ion attractions which are the result of electron exchange
What is ionic bond?
100
measure of the tendency of an atom to attract a bonding pair of electrons
What is electronegativity?
100
The first number in the VSEPR code represents this
What is number of atoms bonded to central atom?
100
Electrostatic force caused by the random motion of electrons
What is London Dispersion?
100
All intermoleculer forces are ------- on the scale of forces compared to intramolecular forces.
What is lower?
200
The bond created when atoms share valence eletrons
What is covalent bond?
200
The most electronegative atom on periodic table
What is fluorine?
200
This type of molecule has overall slightly negative and slightly positive ends called dipoles
What is polar?
200
Electrostatic force of attraction between polar molecules
What is dipole-dipole?
200
The strongest intermolecular force
What is hydrogen bonding?
300
The diagram used to represent ionic compounds and their valence electrons
What is electron dot diagrams?
300
electronegativity determines bond character. This bond occurs if there is no difference in electronegavity.
What is non-polar covalent bond?
300
This type of code represents molecules which are ALWAYS polar
What is bent?
300
A useful quantitative representation of intermolecular bond strength
What is boiling point?
300
The strongest intermolecular force (can be found in diamonds)
What is network covalent?
400
the diagram used to represent molecular compounds and their valence electrons
What is Lewis diagrm?
400
This bond occurs with the greatest difference in electronegativity.
What is ionic bond?
400
Electron repulsion is the strongest between these
What is two lone pairs?
400
The force which increases with greater electronegativity differences within a molecule.
What is dipole-dipole? (due to a more polar molecule overall)
400
Bond formed by the delocalized electrons ( has varying degree on the scale of forces)
What is metallic?
500
The intramolecular bond found in a nitrogen molecule
What is triple bond?
500
The three factors which affect electronegativity strength
What is: 1. # of protons, 2. distance from nucleus 3. amount of electron screening
500
The code 3:1 represents this type of shape AND an example of a molecule with this code is...
What is pyramidal, NH3?
500
The criteria of a molecule which has Hydrogen Bonding.
