1
Q
A
2
Q
Electronegativity
A
The ability of an atom to attract a shared pair of electrons in a covalent bond
3
Q
Metallic bonding
A
- Both atoms have low electronegativity
- Small difference in value
4
Q
Covalent bonding
A
- Both atoms have medium to high electronegativity
- electrons shared fairly evenly
5
Q
Ionic bonding
A
- Big difference in electronegativity
- Electrons are transferred to the atom with high electronegativity
6
Q
The spectrum of bonding
A
7
Q
Coordinate or dative bond
A
Formed when both of the electrons in a shared pair covalent bond are supplied from a single atom (indicted with arrow)
