Chemical Bonding, Formulas, and Compounds Flashcards
1
Q
IntERmolecular Forces
A
Attractive forces between molecules.
2
Q
IntRAmolecular Forces
A
Chemical bonds within molecules.
3
Q
Ionic Bond
A
e- are transferred from metal to nonmetal.
4
Q
Covalent Bond
A
e- are shared between two nonmetals.
5
Q
Covalent Network Bond
A
e- are shared between two nonmetals.
6
Q
Metallic Bond
A
e- are delocalized among metal atoms.
7
Q
Lattice Energy
A
The energy required to break apart one mole of an ionic compound into its constituent ions.
8
Q
Bonding of Metals
A
- Roaming electrons form a “sea of electrons” around
the metal atoms. - Malleability and Ductility
• bonding is the same in every direction.
• one layer of atoms can slide past another. - Conductivity
• from the freedom of electrons to move around.
9
Q
Metal Alloys
A
- Substance that is a mixture of
elements and has metallic properties
10
Q
Substitutional Alloy
A
- Host metal atoms are replaced by other metal atoms.
- happens when they have similar sizes
11
Q
Interstitial Alloy
A
- Metal atoms occupy spaces created between host
metal atoms. - happens when metal atoms have large difference in
size.
12
Q
Dipoles are….
A
- A molecule or a part of a molecule that contains both positively and negatively charged regions.
13
Q
London Dispersion Forces
A
- Attraction between 2 instantaneous dipoles.
- Asymmetrical electron distribution.
- All atoms & molecules.
14
Q
Dipole-Dipole Forces
A
- Attraction between 2 permanent dipoles.
- Polar molecules
15
Q
Hydrogen Bonding
A
- Attraction between molecules with N-H, O-H, & F-H
bonds. - Extremely polar bonds = very strong dipole-dipole
force.
