each dot in an Electron dot diagram represents:
What is a valence electron?
100
measure of the tendency of an atom to attract a bonding pair of electrons
What is electronegativity?
100
molecules adjust their shapes so that valence e- are as far away from each other as possible
What is VSEPR (valence shell electron pair repulsion)?
100
electrostatic force of attraction between the dipoles of polar molecules
What is dipole-dipole forces?
100
a measure of the strength of attraction within or between molecules
What is melting point/boiling point?
200
two electrons side by side in an electron dot diagram represent:
What is a lone pair?
200
The closer one atoms nuclei to other atoms valence electrons are to one another the (greater or lesser) the electronegativity will be.
What is greater?
200

electron pair repulsion is greater between:

What is two lone pairs?

200
The forces of attraction between molecules; weakest of all forces.
What is intermolecular forces?
200
3-D array of alternating positive and negative ions
What is crystal lattice?
300
electrostatic attraction between oppositely charged ions
What is an ionic bond?
300
As you move up and to the right of the periodic table the electronegativity will...
What is increase?
300
linear, trigonal planar, tetrahedral, ......, and .......
What is pyramidal and bent?
300
attraction between a molecule (which contains hydrogen atom covalently bonded to an O, N, F and a lone pair) and another similar molecule
What is hydrogen bonding?
300
cations and a sea of delocalized electrons
What is a metallic bond?
400
formed when two non-metals share a pair of electrons
What is a covalent bond?
400
Bond character can be determine by analysis of a property of electronegativity
What is difference in electronegativity between two atoms?
400
if bond dipoles are equal in strength and opposite in direction they will cancel eachother out resulting in
What is a nonpolar molecule?
400
attractive forces that occur between all molecules resultant on electrostatic attraction of induced dipoles
What is London Dispersion?
400
3-D arrangement of atoms continuously linked throughout the crystal by strong covalent bonds
What is a covalent network?
500
sharing of three pairs of electrons between two atoms
What is a triple bond?
500
polar covalent bonds have slightly posivite and slightly negative ends which are identified using an arrow.
What is bond dipole arrow?
500
The code 3-1 will be polar if the attached atoms have ........... compared to the central atom
What is a different electronegativity?
500
A factor which influences the strength of london dispersion forces
What is size of atom (more e- means more temporary dipoles) OR shape of molecule (more contact b/w molecules = the higher the force of attraction)
500
on the Scale of Forces: ...... is the highest force and .... is the lowest force.
What is covalent network and LD/Dipole-Dipole?
