Ionic, Covalent & Metallic Bonds
Ionic bonds: the attraction between cations and anions is called an ionic bond. In ionic bonds, electrons are transferred from one atom to another in order for it to become stable.
Covalent bonds: one or more pairs of electrons are shared by two atoms
Metallic bonds: formed from the attraction between metal atoms and the surrounding sea of electrons around them. "Electron roaming" takes place within metallic bonds.
Properties of covalent bonds:
-can be soluble in water
-don't conduct electricity in any state
Properties of ionic bonds:
-high melting point
-soluble in water
-conduct electricity as liquid and dissolved but not as solid
-hard and brittle
Properties of metallic bonds:
-not soluble in water
-very high melting point
-conduct electricity in solid and liquid forms
