Bonding, Chemical Formulas Flashcards
1
Q
Potential energy
A
Stored energy
2
Q
Ionic bonds
A
Results from electrical attraction between large numbers of cations and anions
3
Q
Covalent bonds
A
Results from sharing of electron pairs between 2 atoms
4
Q
Polar covalent
A
When electrons are shared unevenly
5
Q
Nonpolar covalent
A
When electrond are shared evenly
6
Q
Lewis dot structures
A
Shows valence electrons used to show bonding
7
Q
Lattice energy
A
Energy released when separate gaseous ion bonds to form ionic solid
8
Q
Metallic bonding
A
Bonding that results from the attraction between metals, atoms, and sea of electrons
9
Q
Ionic compounds
A
- hard: because of strong forces
- higher melting and boiling points
- all solid at room temperature
- brittle: if 1 layer is moved, layers come apart completely
10
Q
Molecular compounds
A
- low melting and boiling point
- many are gases at room temperature
- because of weak intermolecular forces, molecules are easily separated
11
Q
Chemical bond
A
Mutual electrical attraction between nuclei and valence electrons of different atoms that bond the atom together
