What you'll learn
Ionic, covalent and metallic bonding, how each type of structure explains melting point and electrical conductivity, and the distinction between elements, compounds, mixtures and alloys.
- Ionic bonding is electron transfer between a metal and a non-metal
- Sodium chloride shows electron transfer in ionic bonding
- Ionic compounds form a giant lattice held by electrostatic attraction
- Covalent bonding is electron sharing between non-metals
- Simple molecules show single, double and multiple shared pairs
- Metallic bonding is a lattice of positive ions in a sea of electrons
- Structure explains why metals conduct, are malleable, and have high melting points
- Structure explains differences in melting point and conductivity
- Elements, compounds and mixtures are distinguished by composition and bonding
- An alloy is a mixture of a metal with another element
