chemical bonding Flashcards
1
Q
intramolecular bond
A
- a bond occurring between atoms within molecules
2
Q
electronegativity
A
- a measure if the tendency of an atom to attract a bonding pair of electrons
3
Q
covalent bond
A
- a sharing of at least one pair of electrons by two non-metal atoms
4
Q
non-polar covalent (pure covalent)
A
- is an equal sharing of electrons
5
Q
polar covalent
A
- unequal sharing of electrons leading to a dipole forming (as a result of electronegativity difference)
6
Q
ionic bond
A
- a transfer of electrons and subsequent electrostatic attraction
7
Q
metallic bond
A
- a bond between a positive kernel and a sea of delocalised electrons
8
Q
intermolecular force
A
- a weak force of attraction between molecules, ions, or atoms of noble gases
