Electron Affinity vs Electronegativity
A single atom's ability to attract electrons to itself
Electron affinity
Bond in which one loses nearly all its influence on its electrons while the other gains nearly complete influence
ionic
Ionic bonds typically happen between __
metals and nonmetals
Unpaired electrons are called
bonding sites
For most atoms, they want __ valence electrons to be stable
8
Atoms that form covalent bonds have __ electronegativities
similar
Unequal sharing of electrons results in __ bonds
polar covalent
are metallic bonds ionic, covalent, neither
What types of bonds can covalent bonds form
single double triple
Is shape affected by nonbonding pairs of electrons
yes
Electron affinity __ going from left to right
increases
Bonds between two polar molecules which contain hydrogen
Hydrogen bonds
Bonds between any two polar molecules
Dipole-dipole force
Intermolecular bonds that can involve both polar and nonpolar molecules
London dispersion force
As the atomic radius gets larger __ gets stronger
shielding effect
Measurement of an atom's ability to attract electrons to itself from other atoms that it's already bonded with
Electronegativity
Do ionic bonds involve the complete transfer of electrons
no
When atoms within a molecule have partial charges the bonds are __
The shared pair of electrons between atoms are called a
bonding pair
tightly
Electronegativity __ going from top to bottom
decreases
Diatomic molecules will form __ bonds
purely covalent - nonpolar
There is a sea of electrons shared among a mass of bonded atoms in __ bonds
metallic
The weakest of the intermolecular bonds
are metals conductors or insulators
conductors
