Intermolecular Forces
Strongest intermolecular force present in a Cu wire
What is metallic bonding?
Atoms are most stable when their valence electron shell is filled with 8 electrons
What is the octet rule?
The electronegativity difference is 0.0 - 0.2
What is a non-polar bond?
It stands for valence shell electron pair repulsion
What is VSEPR short for?
The 3D structure or arrangement of atoms in a molecule
What is molecular geometry?
An extremely strong force between positive and negative ions
What is an ionic bond?
The electrons in the highest occupied energy level of an atom
What is a valence electron?
1st element is a metal and the 2nd element is a non-metal
What is an ionic bond?
It determines the shape of molecules
What does VSEPR do?
An atom that is bounded to a highly electronegative atom such as nitrogen, oxygen, or fluorine
What is hydrogen bonding?
Hydrogen and helium only need 2 electrons and Boron only needs 6 electrons
What are some exceptions to the octet rule?
The sharing of electrons
What is a covalent bond?
Lewis Structure of the molecule
What determines the shape of a molecule?
The structure has 3 bonded sides and 1 lone pair
What is a trigonal pyramidal?
It is responsible for the attraction within non-polar molecules and are the only forces in a non-polar molecule
What is a London dispersion force?
Atoms will lose or gain valence electrons to make their outer shells full
Why do atoms bond?
A polar bond that includes 1 element and a non-metal
What is a hydrogen bond?
CF4, SiBr4
Of the same geometry, one has 2 lone pairs while the other has 1 lone pair
What is the difference between the two bent geometries?
It has a wide range of boiling points based on the electronegative differences of the atom
What is a dipole-dipole attraction?
A diagram that shows the bonding between atoms of a molecule and lone pairs that may exist within
What is a Lewis Structure?
PCl3 is made up of 2 non-metals
What is a polar bond?
2 bonded sides and 1 or 2 lone pairs
Shape of a bent molecule?
Both structures have the same electron geometry of a trigonal planar
How is the bent geometry related to the trigonal planar geometry?
