Three Types of Bonds
• Three types of bonds we need to know:
• Ionic bonds – bonds between ions to balance out charges
• metal + non-metal
• opposite charges attract
• Covalent bonds – bonds between two non-metals sharing
(“co”) electrons
• Non-metal + non-metal
• Metallic bonds - bonds between two metals
• metal + metal = Alloy!
METALLIC BOND
Very strong “bond” between two
metals atoms
Metallic Bond
•Formed between two or more atoms of
metallic elements
•Electron “cloud” around the metal
atoms
• Sometimes called a “sea of electrons”
Metallic Bonding
• Between Metals bound in a “Lattice”
• An interlaced structure or pattern… but in 3D!
•
• Many metal ions occupy a “fixed” space and electrons
float in- between
• A “sea of electrons” flows between each of the metal elements
A Sea of Electrons
